My little one is 6 months old, she has been in her own room and cot since 2 months old, worked for her , since 2 months ago she wriggles a lot during her sleep and ends up at the top end of the cot , or sideways, half and half, everywhere basically despite being put down at the bottom in a sleeping bag,she's always slept through so from 7pm I never go i to her and this morning I went in and she was face down, to my panic I yanked her up and startled her lol 8 gave a video monitor and do watch her at night but sometimes I'm extra tired and sleep through ... Any ideas?
