DS2 will be 2 at the end of this month. He's had his ups and downs with sleep, but the past two weeks he's been waking around 1am and seems to be suffering separation anxiety or something - he cries, only settling if one of us brings him into bed and cuddles him. However, he doesn't sleep, instead prodding and poking us, and faffing around for up to 2 hours. It gets to the point where we lose our tempers, put him back in the cot where he sometimes cries for a minute or two but mainly goes back.
He has 3 molars still to come, so it could be that. He seems to prefer it with a bit of light on in the room, so perhaps it's a fear thing. He definitely wants company, which makes me think it could be separation anxiety but it seems a bit late...
What is going on? It's driving us mad and we're exhausted.
