DH and I have been co-sleeping with DS since he was about 7 weeks old and we started because I was so sleep deprived from frequent waking for feeds that I could barely see straight. DS is now nearly a year old and we still co-sleep part or all of each night. I admit I'm trying to wean him off some of the co-sleeping but I do what I feel he needs at the time so we just take it one night at a time and I know eventually he'll be in his own bed.
