My Dd is coming up 9 months and keeps waking in the night. She's fairly good at getting herself to sleep in the day. At night she just cant seem to get back to sleep. She has slept well when she's flopped out on our bed on to of the duvet and seems to like te squishyness of it. I know they aren't supposed to have duvets til they are 1yo, but do you think we could get one for her to sleep on top of or is it just a really bad idea?
