Sorry to hear that your having some sleep problems....

With co-sleeping - maddy sleeps between us, we both move our pillow as far over to the side as we can, so we create a space for her in the middle....we put her head right at the top so she would have to move a long way down to go under the doona...she sleeps the BEST with us, but we dont do it often...most morning if she wakes before 6am she comes in with us (thats normally only 5am-6am sleep i dont want to make it a habbit but 5am is to early to be awake!!!

With the gro-bag they are meant to be long so that she can move her legs and kick around...its just like a blanket that cant fall off! its great, as when she comes into our bed, we dont have to worry about blankets for her, as her gro-bag keeps her warm. Maddy is a big gro-bag fan, and sleeps great in them It might be worth a try when she is with you adn ur partner as you wont have to worry about blankets etc...

Good luck with it all, i really hope it gets easier soon.
