My DS1 is 2 1/2 and we transferred him from his crib to his big boy bed (queen bed) about a month ago because he finally started jumping out of the crib. Since this transition he has stopped sleeping through the night and is up AT LEAST 3 times a night. He will not go to sleep unless you lay down with him. He is able to open his bedroom door so we installed an extra tall baby gate in his doorway so that he can't roam around the house in the middle of the night unattended. We had woken up several nights around 3 and 4 AM to him laying in bed with us, or playing in the living room in the pitch black, which prompted the baby gate installation. Since he has been in his big boy bed he wakes up screaming in terror and cannot put himself back to sleep without myself or my husband getting up and laying in his bed with him. We have a very strict nighttime schedule and he is in bed every night at 7:30. We follow the Bath, Milk, Book, Bed routine religiously and have not wavered from it in almost 2 years. We have tried the CIO method, checking on him in intervals of 5 minutes, allowing him to attempt to self soothe before we go reassure him everything is fine... nothing is working. He just stands at the baby gate screaming so loud that he is losing his voice. No one is getting any sleep including our 3 month old son and it seems to be getting worse each night. For the sake of our marriage my husband and I both refuse to sleep in his room with him, even though it would mean more and better sleep for everyone. We don't want it to turn into a bad habit. Help, what can we do to help him stay asleep at night? Its beginning to affect his attitude and his behavior at daycare... Any and all advice is welcome! TIA!!!
