It isn't really any of my business I suppose but... I have a FB friend (well, I know her IRL but haven't seen her in a few years). She is a lot younger than me and she has recently given birth to her fourth baby. I mean, within the last week. And she is posting FB updates to the effect that the newborn is sleeping through the night.
I don't think this sounds normal at all - are there newborns that will sleep all night? If not, should I gently advise her to take the baby to the GP for a checkup?
