S.R.
I have 4 children from 9 to 27 and 2 grandchildren ages 1 and 5. What you are going thru is perfectly normal. He does not like going to sleep by himself because he is most likely scared to be in the room by himself and wants to be near you when he is sleeping. My suggestion is that you tell him he is not allowed to sleep in his own bed anymore."REVERSE PHYSCOLOGY" Give him his blanket and pillow put him on the floor or on the couch in your living room. Tell him it is Quiet time,let him fall asleep watching TV or just being quiet and leave him there for the night. If he wakes up mom, either let him sleep with you or sleep in the same room with him. He will out grow this, lol and sry to say in about 2 to 4 years. Good Luck
And most might think this is a horrible suggestion, put a TV in his room and let him fall asleep with it on, leave it on. This drowns out the noises from the rest of the house and keeps his little mind from worrying about falling asleep or having bad dreams. Again Good Luck, S.
