previously had a good sleeping thing going all by himself, then the last week been waking up crying and ive tried everything and nothing works, he just wants to look around the room and laugh and coo. he rejects feeding, will take a bit of water but still cries when i put him down or leave the room, he has a clean nappy, doesnt take a dummy he sucks his thumb, have given bonjela and calpol for teething still cries. im pretty sure he just wants company and to play, obviously its not playtime at 3am so what to do? thanks in advance.
