Key Takeaways
Postnatal depression (PND) is a clinical condition, not the "baby blues" — the baby blues lasts 1 to 2 weeks and resolves on its own; PND is persistent and requires professional support.
PND affects approximately 1 in 5 Australian mothers, and rates are significantly higher in some populations, including women from South Asian and CALD backgrounds.
Symptoms include persistent low mood, difficulty bonding with your baby, hopelessness, anxiety, intrusive thoughts, and sleep disturbance beyond the demands of a newborn.
PND and postnatal anxiety frequently occur together — both require treatment and both are treatable.
Untreated PND affects not only the mother's wellbeing but also infant attachment and long-term child development — early intervention matters.
CBT is the first-line psychological treatment for PND; ACT and Mindfulness-based approaches are also used effectively.
Medicare rebates of up to 10 sessions per calendar year are available via a GP Mental Health Care Plan — accessing support does not have to be a financial burden.
If you are having thoughts of harming yourself or your baby, please seek help immediately: contact your GP, call Lifeline on 13 11 14, or go to your nearest emergency department.
What Postnatal Depression Actually Feels Like — and Why It Is Not Your Fault
Many of the mothers I see in my practice describe the same experience: they expected new parenthood to be hard. They expected tiredness, adjustment, some difficulty. What they did not expect was to feel profoundly disconnected from their baby. To feel nothing where they had expected to feel love. To find themselves crying without knowing why, or lying awake not from the baby's needs but from a pervasive, shapeless dread.
I have been working with perinatal mental health for a significant part of my 20 years as a registered psychologist, including clinical work with the Gidget Foundation — one of Australia's leading specialist perinatal mental health organisations. In that work I have sat with hundreds of mothers who were struggling in this way. Without exception, almost every one of them had the same question underneath their distress: "What is wrong with me?"
The answer is: nothing is wrong with you. Postnatal depression is a clinical condition with identifiable causes — biological, hormonal, psychological, and social — and effective treatments. It is not a character flaw. It is not a sign you are a bad mother. It is not something you caused by wanting too much, worrying too much, or not being grateful enough. It is an illness. And like most illnesses, it gets better with the right help.
This post is for every new mother who is wondering whether what she is feeling is normal. It is also for partners, families, and GPs who want to understand what PND looks like, how it differs from the baby blues, and what treatments actually work.
Baby Blues Versus Postnatal Depression: An Important Distinction
One of the most common sources of confusion I encounter is the difference between the baby blues and postnatal depression.
The baby blues affect up to 80% of new mothers. They typically begin around day three to five after birth — when the hormonal shift following delivery is most pronounced — and are characterised by mood swings, tearfulness, irritability, and emotional sensitivity. The baby blues are self-limiting: they resolve on their own, usually within 1 to 2 weeks, without any formal treatment. They are a normal physiological response to the dramatic hormonal changes of the postpartum period.
Postnatal depression is different in kind, not just in degree. It does not resolve on its own within a couple of weeks. It persists. It deepens. The symptoms are more pervasive and more disabling. And it requires professional support to treat effectively.
The difficulty is that PND does not always look like what people expect. Some mothers describe it as feeling profoundly empty rather than overtly sad. Some describe it primarily as anxiety — constant, relentless worry about the baby, about their own adequacy as a mother, about everything that could go wrong. Some describe an inability to feel the love for their baby that they expected to feel, which is then compounded by a layer of guilt and shame that intensifies the distress.
If what you are experiencing is still going after two weeks postpartum, or if it is significantly affecting your ability to care for yourself or your baby, please talk to your GP or midwife. What you are describing is almost certainly postnatal depression or postnatal anxiety — and both are treatable.
How Common Is Postnatal Depression? The Figures May Surprise You
One of the things I make a point of telling every mother who comes to see me is this: you are not alone, and you are not unusual.
Postnatal depression affects approximately 1 in 5 Australian mothers — around 15–20% in population-level studies (Beyond Blue, 2020). Postnatal anxiety affects a similar proportion, and the two conditions frequently occur together. When perinatal anxiety and depression are considered together, the prevalence in some populations is significantly higher.
What the national figures also show — and what my clinical experience confirms — is that rates of PND are significantly higher in certain groups. Women from culturally and linguistically diverse (CALD) backgrounds, including South Asian and migrant communities, often face additional risk factors: social isolation, language barriers, distance from extended family networks, the specific pressures of cultural expectations around motherhood, and the difficulty of accessing services that understand their cultural context.
In my clinical work with perinatal clients, and in my work with the Gidget Foundation, I have worked extensively with women from Indian, Sri Lankan, Pakistani, and other South Asian backgrounds who were experiencing PND in the context of these compounding factors. In many cases they had been struggling for months before seeking help — often because of stigma, because they did not recognise what they were experiencing as an illness, or because they had not found a clinician they felt they could speak to.
If that describes your situation, please know: help is available, Medicare rebates cover it, and I offer sessions in Hindi, Marathi, and Punjabi as well as English.
Symptoms of Postnatal Depression: What to Look For
PND presents differently in different women. There is no single checklist that captures every presentation. But the following symptoms, particularly when persistent (lasting more than two weeks) and significantly affecting daily functioning, should prompt a conversation with your GP or a psychologist.
Mood symptoms:
Persistent low mood, sadness, or emptiness that does not lift
Hopelessness — feeling that things will not get better
Loss of interest or pleasure in activities you usually enjoy
Feeling detached, numb, or "going through the motions"
Crying frequently, or being unable to cry at all
Anxiety symptoms:
Excessive, uncontrollable worry — particularly about the baby's health and safety
Intrusive, distressing thoughts (often about something bad happening to the baby)
Feeling constantly on edge or unable to relax
Physical symptoms of anxiety: racing heart, tight chest, shortness of breath
Bonding and relational symptoms:
Difficulty feeling connected to or loving toward your baby
Feeling like you are going through the motions of caring for the baby without emotional connection
Feeling overwhelmed by the demands of mothering and unable to see an end to it
Functional symptoms:
Sleep disturbance that goes beyond the demands of a newborn
Appetite changes — eating very little or using food for comfort
Difficulty concentrating or making decisions
Loss of energy and motivation far beyond normal postpartum tiredness
In severe presentations:
Thoughts of self-harm or suicide
Thoughts of harming the baby
The last two require urgent attention. Please contact your GP, call Lifeline on 13 11 14, or go to your nearest emergency department immediately. These thoughts are a symptom of illness — they do not reflect who you are as a person or a mother — but they require immediate professional support.
Postnatal Depression and Postnatal Anxiety: Understanding the Overlap
One of the most important clinical observations from my perinatal work is that postnatal anxiety is often more prominent than postnatal depression in the early postpartum period — and it is often missed, both by mothers themselves and sometimes by professionals, because it does not fit the familiar picture of "depression."
Postnatal anxiety involves intense, persistent worry about the baby's wellbeing, constantly checking and rechecking, difficulty tolerating uncertainty, intrusive thoughts about harm coming to the baby, and physical symptoms of anxiety. It can be exhausting and disabling, even when the mother appears to be functioning adequately from the outside.
PND and postnatal anxiety frequently co-occur — research suggests they co-occur in approximately 30–40% of perinatal presentations (Falah-Hassani et al., 2017). When they occur together, treating only one without addressing the other typically produces incomplete outcomes. My clinical approach in perinatal presentations always involves a thorough assessment of both anxiety and depression, and a treatment plan that addresses whichever components are most prominent.
Risk Factors: What Increases the Likelihood of PND
PND does not have a single cause. It arises from a combination of factors, and understanding these is important both for identifying who may need more support and for reducing the shame that many mothers feel when they develop it.
Biological and hormonal factors: The dramatic drop in oestrogen and progesterone following birth is a significant biological trigger. Sleep deprivation, which is universal in new parenthood, significantly affects mood regulation. Women with a personal or family history of depression or anxiety are at elevated risk.
Psychological factors: A history of depression or anxiety is the single strongest individual risk factor for PND. Perfectionism and high self-standards ("I should be handling this better"), negative cognitive styles, and difficulty tolerating uncertainty also increase vulnerability.
Social and relational factors: Lack of practical and emotional support from a partner, family, or community. Relationship difficulties. A difficult or traumatic birth. Social isolation. Financial stress. Being far from extended family — particularly common in migrant communities.
Cultural factors: For women from South Asian, Indian, and other CALD backgrounds, specific cultural pressures around motherhood — expectations of constant selflessness, stigma around mental health, lack of culturally appropriate services — create additional barriers to both recognising and seeking help for PND.
None of these factors are things a woman chooses or causes. They are the conditions that increase vulnerability. Understanding them reduces blame and enables earlier, more targeted intervention.
Treatment: What Actually Works for Postnatal Depression
PND is a treatable condition, and there is good evidence for several approaches.
Cognitive Behavioural Therapy (CBT) is the first-line psychological treatment for PND and the approach with the strongest evidence base. CBT for PND addresses the negative automatic thoughts that maintain low mood and anxiety (including thoughts about being a bad mother, about the baby being at risk, about the future being hopeless), builds behavioural activation to re-engage with meaningful activities, and develops practical coping strategies. A meta-analysis by Sockol (2015) found that psychological treatments — particularly CBT — were significantly more effective than control conditions for PND, with moderate to large effect sizes.
Acceptance and Commitment Therapy (ACT) is particularly useful when a mother is struggling with the gap between the experience she expected and the experience she is having — when guilt and self-criticism are prominent, and when acceptance of the complexity of new parenthood is the key therapeutic task.
Mindfulness-based approaches are supported by growing evidence for perinatal mental health and are particularly useful for anxiety and rumination. I integrate mindfulness practices into my perinatal work as a component of CBT and ACT — not as a standalone treatment, but as a skill that supports the broader therapeutic work.
Psychoeducation for partners and family is an often-overlooked component of PND treatment that I consider essential. When partners understand what PND is, what it is not, and how they can help, outcomes improve significantly. I involve partners in the psychoeducation component of treatment wherever possible.
Medication, when indicated, is prescribed by a GP or psychiatrist. I work collaboratively with prescribing doctors and communicate clearly about what I observe in sessions. For some women — particularly those with moderate to severe PND, or those who are not able to engage with psychological therapy due to the severity of their symptoms — medication can be a necessary scaffold. The decision is always made by the woman in partnership with her medical team.
Why Early Intervention Matters
I want to be direct about this: the research evidence on untreated postnatal depression is clear, and it matters beyond the mother's own wellbeing.
Untreated PND is associated with disrupted infant attachment — the foundational relationship that shapes a child's emotional and cognitive development in the first years of life (Murray et al., 2010). When a mother's depression prevents her from being consistently emotionally available, responsive, and engaged, the infant's developing brain and nervous system are affected. Longitudinal studies show that children of mothers with untreated PND have elevated rates of emotional and behavioural difficulties in childhood and adolescence.
This is not said to increase guilt — it is said to underscore urgency. Getting support for PND is not a self-indulgence. It is one of the most significant things a mother can do for her child.
Medicare rebates make psychological treatment accessible. A GP referral for a Mental Health Care Plan provides up to 10 sessions per calendar year. The Gidget Foundation also offers funded psychological support specifically for perinatal mental health, including a telehealth service called Start Talking, available free of charge.
Test Your Understanding
How I Can Help
Perinatal mental health is an area of genuine clinical depth for me. My work with the Gidget Foundation gave me experience across the full range of perinatal presentations — from subclinical anxiety in pregnancy through to severe postnatal depression and perinatal loss. I bring that experience to every perinatal client I see.
I offer CBT, ACT, and Mindfulness-based approaches tailored to the specific needs of each mother. I involve partners and family in psychoeducation where appropriate. And I work collaboratively with GPs, obstetricians, and psychiatrists to ensure treatment is coordinated and comprehensive.
I see clients at Potentialz Unlimited in Bella Vista, Unit 608, 8 Elizabeth Macarthur Drive, with after-hours and Saturday appointments available. Telehealth is available via phone or Zoom.
Medicare rebates are available with a GP Mental Health Care Plan — up to 10 sessions per calendar year. I also accept WorkCover, NDIS, and EAP/EPP referrals.
I speak English, Hindi, Marathi, and Punjabi. For mothers from South Asian and migrant backgrounds who would feel more comfortable receiving care in their own language, I welcome the opportunity to provide that.
