He's been awake since 1am (and woke at 10.30pm too, just as I was drifting off to sleep) he's been awake for 2.5hrs at this point. Just cuddling and staring into space / feeding now and again. Why won't he sleep arrrghhhh. He woke up really late yesterday at 9.30am (usually around 7am) and didn't nap all day (would usually do a nap after lunch for anywhere from 30mins to 2hrs). Maybe that's why? If I try and put him in the cot he's quiet for about 10 mins then starts crying again. I don't do sleeping training / cry it out so won't leave him to do that. He's 19 months. So tired.
