Ten month old won't settle

[kbx201]

Starting to really struggle with my ten month old during the night. He goes in his cot at 7pm and sleeps for a couple of hours at which point I take him into bed with me. He used to sleep really well but for the last month or so he’s been waking at 10-11pm and he is so unsettled, constantly thrashing, kicking and rolling about for hours. He’s not fully awake but he’s not asleep either, and I’m getting no sleep. Tried putting him back in the cot in case he was ready to sleep in his own bed but he’s even worse in there. Why is he doing this? He was teething at the start of this but not anymore, he’s got 8 teeth so surely no more for a while? he’s not ill or hungry. I’m so tired and starting to dread bedtime. I won’t leave him to cry it out, is it just a development thing?

When you say he's not asleep but not fully awake either is he crying or do you just lift him, if he's not crying when he's doing this I would leave him until he crys he might settle again r minds go through different sleep patterns through the night, like in a deep sleep then not back to deep sleep so could be he's not in a deep sleep at that stage.
