I've gone back to feeding 13 mo DS again, around 4.30-5am. If I don't, he (and I) just have really broken sleep from then till morning (6ish).
Other night wakings, he gets water and a cuddle, which seems fine.
Sleep used to be absolutely dreadful. 2 hourly wakings until he was about 11 months. So this is a big improvement. Concerned he'll start waking more and more for it though.
