My DS is 5months old. He has been sleeping great from 2months, went down around 7.30pm right through till 6am. I used to be able to put him down in his cradle and he would fall off by himself but now I have recently moved him into his cot and its just a screaming match when he goes down. Ive tried staying with him and talking to him, also have tried letting him cry which was really hard but he just gets really upset, only way I can get him off is by holding him until he's nearly asleep and then put him down, where he will sleep right through to 6am. I know holding him until he's nearly asleep is a bad habit to get into, help!
