Ds has always been a bad sleeper however from around 8 months he's been good at going to bed (around 7)
From about 18 months he was sleeping through around 5 nights in 7. This was when he moved to his own room.
But the last couple of months it's been awful and he won't go to bed. When I leave the room he smashes his head against the cot (hard enough to leave a bump).
I won't leave him to cry but don't pick him up. Just soothe in the cot but most the time he's happy just not wanting to sleep even when he's so tired.
Nothing seems to make any difference. (Naps etc). He's had some of his best nights with no maps and with long ones.
He's very vocal and able to tell me when he's hungry , thirsty, hot or cold but it's never any of these things when we have an awful night.
I thought this was just a phase but it's been 2 months! He will occasionally have a bf but not much now.
Any advice? He's 21 months.
