2yr old wont sleep at night

[candy11]

I have a 2yrs old boy who for the last 4 months ish has been waking through the night, he will go to bed between 9-9.30pm (before that and he will be up at stupid o'clock) them at about 11.30pm he will start waking and coming in to mine and daddy's room, one of us will get up and put him back to bed, this will continue for a while, then he will eventually fall back to sleep, but and hour or so later this will happen again, he gets up about 10.20 times a night. we have tried everything eg nightlight/no nightlight, making him warmer/cooler, asking him why he is waking but getting no answer, taking to him hen we put him back to bed/ not taking to him. stopping his naps during the day so he is more tired but it doesn't work. I just don't know what to do anymore none of us are getting any sleep and we are all grumpy because of it. please help me!!!
thanks in advance

Do you do a bedtime routine? Like quiet time,winding down before. With maybe a bath and story?

yes we have done since 9 weeks old, he has a bath every night then a bed time story. the going to sleep is not a problem its the staying asleep that's the issue.

You should look up if its ok .... But I use to put a drop of lavender oil on a tissue next to mines pillow . He love it!! Got to the point of I need my drops lol. I used control crying while he was in the cot still though.
