We have been having this problem from the beginning. He will not sleep in his crib and is almost too big for his bassinet. He has been teething for over a month now but I know that doesn't have much to do with it since he's always been a poor sleeper...we have tried everything...and I mean EVERYTHING and nothing works or helps. I'm at my wits end and feel as if I'm going to go crazy. He barely naps as well so I know he's overtired. Anyone still having an issue similar? He has also started to scream very loud so I'm not sure what is going on...
