Hi,
My 4 week old son is having trouble sleeping at night. He will happily fall fast asleep in my arms but as soon as I put him in his crib he wakes and cries. When I pick him up he will stop and fall back to sleep. He is in a Chicco next to me crib and I have tried keeping contact with him (hold his hand, rub his belly, stroke his head etc) to try help him fall back asleep without picking him up and I've also tried letting him cry it out but he gets himself that upset he will then be sick. Does anyone have any other suggestions/advice??
