My youngest son is 3 and I have co slept with both my boys. My oldest moved into his own bed when my youngest was born, maybe a lil before then. We were able to share a full size bed as Dad works nights. I have been trying to get my youngest to sleep by himself in his twin bed. He will fall asleep and sleep for about 4 hours then he comes and finds me. Do you have any suggestions on how to get him to sleep all night in his own bed? We are expecting our 3rd in november, and I am going to need him in his own bed all night. Thanks soooo much!
