Parent Mental Health & Postnatal Wellbeing
Postnatal mental health difficulties affect around 1 in 5 new mothers and 1 in 10 new fathers. They are not a sign of weakness, inadequacy, or bad parenting. They are treatable. And getting help is one of the most important things you can do for your baby as well as yourself.

The baby blues — a short-lived period of tearfulness, emotional lability, and low mood that typically begins around day 3–5 after birth and resolves within two weeks — affect around 80% of new mothers. They are driven largely by the dramatic hormonal shift that follows delivery and the physical aftermath of birth. Feeling weepy over a television advert on day four is not postnatal depression.
Postnatal depression (PND) is distinguished from the baby blues by its persistence, severity, and impact on daily functioning. It typically develops in the first three months after birth, though it can emerge up to a year postpartum. It does not resolve on its own in a fortnight. And it looks very different from what most people imagine when they picture depression.
What Postnatal Depression Actually Looks Like
The cultural image of postnatal depression — a mother unable to get out of bed, unable to care for her baby, visibly distressed — represents the more severe end of the spectrum. Many people with PND are functioning: caring for their baby, managing the day, turning up to health visitor appointments. They just feel terrible while doing it.
PND can present as persistent low mood, but also as emotional numbness, flatness, and a sense of going through the motions without feeling present. It can look like relentless anxiety and difficulty switching off, rather than sadness. It can look like irritability and anger that feel disproportionate. It can look like an inability to feel the love for your baby that you expected to feel, followed by enormous guilt about that absence.
My postnatal depression did not look like sadness. I felt nothing. A kind of grey flatness that meant I went through all the right motions — feeding, bathing, nappies — while feeling completely absent from my own life. I didn't recognise it as depression until a friend named it for me. It doesn't always look the way you expect.
Common signs of PND worth recognising
- Persistent low mood, crying, or emotional numbness that does not lift
- Difficulty sleeping even when the baby sleeps, or difficulty getting out of bed
- Loss of interest or pleasure in things you usually enjoy
- Feeling detached from your baby, or from yourself
- Intrusive thoughts about something bad happening to the baby
- Feeling overwhelmed, hopeless, or unable to cope
- Anxiety that feels constant rather than situational
- Anger or irritability that feels out of proportion
Postnatal Anxiety
Postnatal anxiety is at least as common as postnatal depression and receives considerably less attention. It can occur alongside PND or on its own. For many people — particularly those who did not experience significant anxiety before — the intensity of postnatal anxiety is completely unexpected.
It can present as an inability to stop worrying about the baby's safety, health, or development; intrusive thoughts about harm coming to the baby (which are extremely distressing and not a sign of danger to the baby — they are a symptom of anxiety); a need for constant reassurance from partners, health professionals, or online searches; physical symptoms of anxiety including racing heart, tight chest, and nausea; or hypervigilance and difficulty relaxing even when the baby is settled and safe.
Paternal Postnatal Depression
Postnatal depression affects around 1 in 10 new fathers and partners, with some research suggesting rates as high as 1 in 4 during the first year. It is significantly under-recognised because it is rarely screened for, because men are less likely to present with distress, and because the cultural script of fatherhood does not include vulnerability.
Paternal PND often presents differently to maternal PND: more commonly as irritability, anger, withdrawal, and increased use of alcohol or other avoidant behaviours than as visible sadness. Partners who throw themselves into work in a way that seems disproportionate, who become more distant, or who seem angry about relatively minor things may be struggling with something they do not have language for.
I had postnatal depression as a dad and I didn't tell anyone for four months because I thought it was only something that happened to mothers. I thought I was just finding it hard, or being weak. When I finally told my GP he said paternal PND affects around 1 in 10 new dads. I wish I'd known that earlier.
Partners who are worried about their own mental health can speak to their own GP — they are entitled to assessment and support in their own right, independently of what the birthing parent is experiencing. PANDAS Foundation (0808 196 1776) supports partners as well as mothers.
Post-Traumatic Stress After Birth
Around 4% of women develop PTSD following childbirth, with a further 18–30% experiencing some PTSD symptoms without meeting the full diagnostic criteria. Birth trauma is not defined by what happened objectively — it is defined by the subjective experience. A birth that looks uncomplicated on paper can be experienced as traumatic, particularly if the person felt out of control, disrespected, or frightened.
Symptoms of birth-related PTSD include intrusive re-experiencing of the birth (flashbacks, nightmares), avoidance of reminders of the birth, hypervigilance, and emotional numbing. These symptoms can make the postnatal period extremely difficult and can affect bonding, feeding, and the relationship with a partner. Effective treatments — particularly EMDR (Eye Movement Desensitisation and Reprocessing) and trauma-focused CBT — are available on the NHS through perinatal mental health teams.
Getting Help
If you recognise yourself in any of this, the next step is to tell someone — your health visitor, your midwife, or your GP. Being specific is helpful: "I think I might have postnatal depression" or "I've been having a lot of anxiety and intrusive thoughts" gives a clinical professional a clear starting point. You do not need to have all the answers; you just need to open the door.
What treatment might involve
- Talking therapies — CBT (Cognitive Behavioural Therapy) and counselling are available through NHS Talking Therapies (formerly IAPT) with a GP referral, and through some perinatal mental health teams directly.
- Medication — several antidepressants are safe during breastfeeding and have an extensive evidence base in the postnatal period. This is a conversation worth having with your GP without ruling it out in advance.
- Perinatal mental health teams — specialist multidisciplinary teams available through NHS trusts for people with moderate to severe perinatal mental health difficulties.
- Mother and baby units (MBUs) — specialist inpatient settings for severe perinatal mental illness where mother and baby can be admitted together. These are a last resort but exist precisely because keeping the mother-baby dyad together is important.
I resisted antidepressants for three months because I was breastfeeding and terrified. Then a perinatal psychiatrist explained that sertraline has more data on safety in breastfeeding than almost any other drug in existence. I took it. Within six weeks I recognised myself again. Please don't let fear of medication be the thing that keeps you unwell.

This is one of the most common questions, and it does not always have a clean answer. A useful frame: finding it hard — being exhausted, overwhelmed, occasionally tearful, daunted by the responsibility — is a normal response to an objectively demanding situation. PND is when those feelings are persistent (most days, for more than two weeks), pervasive (colouring your entire experience rather than coming and going), and impairing (making it difficult to care for yourself or your baby, or making you feel that your baby would be better off without you). If you are in any doubt, speak to your health visitor or GP. The cost of raising it is low; the cost of not raising it can be high.
Yes, in many cases. Sertraline and paroxetine are the most widely studied antidepressants in breastfeeding and are generally considered low-risk, as very little passes into breast milk. Fluoxetine is used more cautiously. The decision should be made with your GP or a perinatal psychiatrist, weighing the risks of the medication against the risks of untreated illness. Untreated postnatal depression has its own effects on the mother-baby relationship and infant development — these need to be weighed too.
Yes. Anger and irritability are recognised symptoms of depression, and in postnatal depression they are common — often more prominent in people who do not match the classic tearful presentation. Feeling disproportionately angry at your partner, at small inconveniences, or at the baby, in a way that does not feel like you, is worth raising with your GP or health visitor. It is a mood symptom, not a character flaw.
This is a painful and unfortunately common situation. The most direct route is to speak to your GP or health visitor yourself, without waiting for your partner to agree that there is a problem. A clinical assessment and a professional conversation about what you are experiencing may help your partner understand in a way that your own communication has not. If your partner continues to minimise your experience, that is worth addressing as a relationship issue — a couples therapist or GP conversation that includes both of you may help.
