Ds is 4, have always put him to bed and he goes straight to sleep and he slept through the night.
Recently had started waking 3/5 times a night before I went to bed, then once I was in bed would sneak into my room.
He wriggles a lot so kept trying to get him back in his room but he'd keep returning.
These last couple of nights have been awful. He has become extremely extremely clingy to the point I can not leave his sight during the day. When I go to bed he is hysterical saying if he closes his eyes he can't see me, so he can't close his eyes. The other night he was up until almost 5am (broken sleep between) then dd was up at 6.30 
I feel awful but tonight I ended up telling him off because he was not calming down
I'm just so so tired.
Has anyone got any advice? Please?!
