The postnatal period is different for all mothers. Although perhaps some women find the transition easy, if I am honest I cannot think of
anyone I know who has not found it coming with some form of challenges along the way, e.g. with breastfeeding/sleep etc. Recently the discussion around this has become much more honest, with
several high profile celebrities speaking out about the realities of having a new baby, and allowing the idea that it is absolutely okay, if not totally normal, to feel pretty out of sorts at
times and to need some support.
Part of the work I do with families, regardless of it being a first baby or a third, is making a postnatal plan and preparing properly for the postnatal period. Having realistic expectations and being able to ask any questions about this time is hugely important in making the transition as smooth as possible. There are some more thoughts on this here.
