The past week my 4 month old will only fall asleep for dad. With me he cries and cried and as soon as dad takes over he's instantly calm and drops off easily. I used to breast feed until a month ago and fed to asleep and we now share bottle feeding and he is rocked until drowsy then put down and shushed, patted. If this is the dreaded 4 month sleep regression why is he only being difficult for me? I'm trying not to take I personally but it's hard not to wonder if I've done something wrong.
