DS has been a chronic bad sleeper but he did improve briefly around the 22-24month mark and then went downhill again. He has been doing similar lately, wanting to get into bed with us, needing to be in direct physical contact, staying awake for hours at a time (although that is not new here).

I have about a million theories about sleep LOL but one thing that has occurred to me recently is that this could be a cognitive development thing. He is the same age as your DD and I have wondered whether it is his imagination that is now keeping him awake (or preventing sleep in the first place). He has been exposed to heaps of stuff at child care but even at home we read lots of stories every day and he does watch some TV as well. Atm, he is particularly into bear stories and the gruffalo, he pretends to be a bear or the gruffalo or pretends that he is being chased by them etc. There is lots of falling into rivers and running through fields and falling over and needing help and caves and....you get the idea. This is during the day I'm talking about but I have been wondering if he is also thinking of this stuff at night time too? Hence the need for greater reassurance. He can imagine scary type stuff anytime he wants to now.

I hope it passes quickly for you. DS is also an annoying bed companion and needs to be lying some part of his body over mine. We have to face him too otherwise he climbs up on our heads (usually mine) and lays his cheek on my cheek

ETA - Can I send DS south to attend that sleep over by any chance lol
