Postpartum psychosis is just a normal baby blues

What the research found

Official guidance describes baby blues as mild mood changes that are normal and usually last only a few days. It says postpartum psychosis is very different. It is a serious mental illness and should be treated as a medical emergency. Symptoms can include hallucinations, delusions, mania and severe confusion.

Reviews published in 2023 and 2024 describe baby blues as low mood and mild, short-lived, self-limited symptoms. One review put the overall rate at 39%, ranging from 13.7% to 76%. Postpartum psychosis is far rarer, at around 1 in 1000 women. A 2017 systematic review reported 0.89 to 2.6 per 1000 women. Symptoms usually appear within 2 weeks of birth.

Untreated postpartum psychosis carries real risks. A 2025 systematic review reported a 4% infanticide rate when it goes untreated. Clinical guidance says it can get worse rapidly and can risk the safety of both mother and baby. Most people make a full recovery with the right treatment, often in hospital.

What it doesn’t mean

• Baby blues can sometimes lead to more serious conditions, so ongoing low mood after the first days is worth raising with a GP or child health nurse.
• Someone with postpartum psychosis may not realise they are unwell. Partners, family and friends may need to spot the signs and act.
• If a new mother has sudden confusion, hallucinations, unusual beliefs or extreme highs, see a GP urgently the same day. If anyone is in danger, call emergency services.
