Saffron, thank you for raising that very useful point about postnatal depression. I agree that PND goes undiagnosed far too often and that too many mothers suffer in silence, alone and with an unnecessary sense of shame and guilt. It is shocking to me that mental health in general is such a taboo and PND in particular, because having a baby is sold to women like a time when they should be happy and gratified, no matter what. What I suppose the NICE guidelines are trying to do quite badly is make a distinction between 'baby blues' and PND. Baby blues tends to develop straight after birth (up to ten days) due to hormonal changes, the need to adjust to a new life phase, the demands of a new baby, an unprecedented amount of tiredness and lack of sleep, etc. It consists of mild symptoms which are manageable and normally go away on their own. It is so common now that is is considered normal. I would say the operational word here is manageable. PND is instead a mental illness which develops slightly later (up to six weeks) with much more severe symptoms which are unmanageable and just doesn't go away by themselves. It presents itself with the usual signs of depression plus some specific ones like thoughts of harming the baby which can be frightening and incomprehensible, making PND even more of a taboo to talk about. And as you say, this is when, sometime, undiagnosed and untreated PND can lead to psychosis with grave consequences. I urge every mother who experiences persistent unmanageable symptoms to talk to their health visitors, midwives, or GP all of whom should have access to the Edinburgh Postnatal Depression Scale questionnaire. PND is not a sign you have failed in any way or that you are less of a mother. It is a common mental health condition that affects almost a third of all mothers especially if they have a history of previous mental health, abuse, low self esteem and have no support. Seeking help is a sign of strength and care for yourself and your baby. Talking to someone is the first step to feeling better. Barbara, from NestLondon
