Has he got a night light in his room? Our DD#1 wouldnt settle with out it and even now we still use one (its handy for when you want to check on them through the night).

There must be a reason for him being so hysterical at night but finding out what the problem is is hard trying to get a 2yr old to tell you. Even though our DS is 2 and speaks *really* well, theres no way he would be able to tell us what is wrong if there were a problem like that. Kids cant communicate like we can. Thats the frustrating part.

Does he still have day sleep, if so does he cry for that to?Has this started since daycare?. Have you tried staying with him till he goes to sleep then leaving the room?
And once he is asleep is he then ok?
