I see the date on your post for your 2 year old sleep problems was dated back to 2002. I have the same issue with my 26 month old. One day she wouldnt go to bed in her crib. She would cry and cry for hours. She began to climb out of the crib, so we dropped the mattress to the floor on the crib, and she still managed to get and hurt herself falling out. So we moved her mattress into our room, helped for awhile and now she is in bed with us. but she still wakes up at 2-4am. Whining constantly, wanting milk. I have a 4 yr old and a 6 month and its making it difficult for everyone. What did you do to fix your problem? Any advice?
