The National Childbirth Trust (NCT) has published The hidden half: bringing postnatal mental illness out of hiding.
The Hidden Half campaign surveyed 1,000 women who had recently had a baby and found that half had a mental health or emotional problem postnatally or during pregnancy. Of these, nearly half hadn’t had their problem identified by a health professional and hadn’t received any help or treatment. Many of these new mothers said they were too embarrassed or afraid of judgement to seek help.
