My baby developed colic at 3 weeks of age , well we've been blessed enough that he is pretty much over it now but he's gotten so used to sleeping on me since with colic I couldn't get him to sleep any other way that now he will not sleep anywhere but on me or beside me !! I'm terrified of this but he has to sleep and idk how to break him of it and get him sleeping in his bassinet or crib. 
Has anyone else went threw this and what can I do to get him sleeping in his own bed ???
