I am starting to feel he has a baby version of insomnia! Brief background: he has always been a difficult sleeper but lots of patience (mostly) and time and he has got much better. He's currently almost 20 months. Recent,y he is clearly going through a massive developmental leap that started with sleep regression at 18 months. Since then he's gained a lot of new skills, words etc and has clearly been fuelling all this with a large increase in how much he eats.
So all good, and understandable but he simply isn't going to sleep at night. He's not crying but he's awake still and I put him down at 7:15. I went in at 8:30 and gave him a little extra milk but he's still awake. I don't know what to do. This can't be good for him but why isn't he sleeping?
