DS2 moved himself into DS1 room when he was 26 or 27 months, got into DS1 bed and refused to get out. They shared kind single for 3 months before DS2 started scratching DS1 face and annoying him so eventually convinced them that moving DS2 bed into same room could be done. So we moved his bed.

They were very good for 9months and easy to put to bed but for last few months bed time is a NIGHTMARE they changed PJ's get toys out, jump on bed annoy each other etc and often ends up with DH having 1 in our room and me sitting with other in there room then transfering to bed!!

They do love it thought. We have tryed seperating again and it doesn't work unless we stay with each till asleep so i hope this soon will pass!
