DS still wakes 1-3 times a night (normally twice), EBF a week away from being 5 months old and my period has returned today. With DD it was around 7 months when she started sleeping through (not keen on solids until a year old). Why oh why, had hoped to make it to a year this time. I wonder if it has anything to do with fertility. DH seems to have to just look at me and I'm pregnant even though I am about to leave my 30s. Was hoping for a bit longer. Does anybody know why this happens to some women. Sleep deprivation, a teething baby (first tooth emerged today) and a toddler to look after, the last thing I need is my period .
