My 9mo has been sleeping through the night since 8wks old. He gets his bath then bf and 8 out of 10 times used to fall alseep but if not, I could always put him down in his cot awake and he would just play with his teddies for a while and then fall alseep. For the last 3 weeks he hasn't fallen asleep after being fed and screams the place down when put in his cot. I try to leave him but can only last 5 mins because he starts to choke due to screaming so much. When I go to get him he is standing up holding onto his cot railings and I then have to feed him again until he falls asleep. I don't know what to do and he's even started screaming during the day now if he's tired and won't go down for his naps. Any ideas?
