Postnatal Depression: Signs, Support and Treatment

Postnatal depression is one of the most common complications of having a baby, and one of the most treatable — yet it's still often talked about quietly, or mistaken for something you should just push through. It affects partners too, not only birthing parents.

Baby blues vs postnatal depression

The "baby blues" — tearfulness, mood swings, feeling overwhelmed — are extremely common, affect the majority of new parents, typically start around day 3-5 (often linked to the hormonal shift as milk comes in), and usually pass within about two weeks without treatment.

Postnatal depression is different: it can start any time in the first year (not just the first weeks), tends to persist rather than pass, and is generally heavier and harder to shake — low mood most of the day, most days, for two weeks or more is the rough clinical threshold, though you don't need to wait that long to ask for help if something feels wrong.

Signs to look out for

• Persistent low mood, sadness, or feeling numb, most of the time
• Loss of interest or pleasure in things you'd normally enjoy
• Overwhelming tiredness that rest doesn't fix
• Feeling unable to cope, or that you're failing as a parent
• Guilt, worthlessness, or being unusually self-critical
• Difficulty bonding with your baby, or feeling disconnected from them
• Withdrawing from friends, family or your partner
• Changes in appetite or sleep beyond what's explained by having a newborn
• Frightening or intrusive thoughts (common, and rarely acted on — but always worth telling someone about, not hiding out of shame)

It affects partners too

Postnatal depression isn't limited to the parent who gave birth — partners can and do experience it, often under-recognised because attention naturally focuses on the birthing parent and baby. The same signs and the same support routes apply.

What genuinely helps

• Talk to your health visitor, midwife or GP — they ask about this specifically at routine checks for exactly this reason, and would rather hear about it early than have you struggle alone.
• NHS talking therapies, including CBT, are available by self-referral in most areas — you don't need to wait for a GP appointment to start that process.
• Specialist perinatal mental health teams exist in most areas for anything more than mild-to-moderate, offering more intensive support.
• Medication is sometimes appropriate, including while breastfeeding — several antidepressants are considered compatible; this is a conversation for your GP, not something to rule out or self-manage based on assumption.
• Peer support groups (in person or online, including PANDAS Foundation, a UK charity specifically for perinatal mental illness) genuinely help many parents feel less alone.

For the people around a new parent

If someone close to you seems to be struggling, gently naming what you've noticed and offering to go with them to a GP appointment can make the first step much easier — many parents delay getting help simply because starting the conversation feels hard.

If it feels urgent

Contact your GP, health visitor or NHS 111 immediately if you're having thoughts of harming yourself or your baby, or if you feel unable to keep yourself or your baby safe — this is treated as urgent, and help is available immediately, day or night. HealthAnswers' guide to postnatal depression covers symptoms, the difference from the rarer but more serious postpartum psychosis, and treatment options in more clinical depth.
