At what age did you leave your baby/child to sleep on their own?

DH did the night sleeps, I fed DS on the end of DD's bed while she went to sleep for naps. Before she was born I lay with her, but she seemed to understand and accept that I couldn't lay down when I needed to hold him and he would cry if I left him alone (and she hated him crying so got that we needed to have him in for cuddles too!).

DD1 was fed to sleep till she weaned at 3yrs 3mo. We are now able to leave her to fall asleep alone, she is even happy enough to get up to the toilet on her own overnight. When we had both girls, I would either have DP hold DD2 while I fed DD1 or take DD2 in with me and feed both at once, occasionally DP would settle DD1 if required. DD1 fed overnight till she was 2yr 9mo which was luckily a few weeks before DD2 arrived.
