Hi, I'm a first time mum, my son will be 5 weeks on Thursday. The past 2 days he has been particularly cranky and fussy. Go through the usual is he hungry, does his nappy need changed, is he warm/cold but nothing seems to settle him. He takes forever to settle down for a sleep, almost as if he fights it. Only way he will stay asleep is lying on me. Could this be him going through his first 'leap' early? Anyone have any experience with this? Thanks
