So, DS is just over 2yo and has never been a great sleeper.
He would go down fine in his cot and then wake at some point in the night and we would co-sleep from then on.
TBH, we just found the co-sleeping so tiring as the bed wasn't really big enough and DH and I just found ourselves constantly being kicked or pinched in the night.
So last week we did some shifting around of beds and he is now in the bottom bunk with DS2 on the top one.
The tricky thing is trying to get him off to sleep without me lying next to him. He goes in fine, has a story, a quick bf and then pats his pillow and wants me to lie next to him. Otherwise he gets upset and tries to get out of the room.
I totally get that going from partial co-sleeping to a bed is a bit of a big leap for him so maybe I am expecting too much from him?
I just have horrible visions of having to lie next to him for every night from now on and never being able to go out or do anything until he is asleep!
He still wakes in the night several times so now instead of him being in our bed, I'm spending half the night in his. 
Can anyone give me some tips or reassurance that things will get better?
TIA
