ok so since DS born we used grobags...excellent love them not got a problem there but since he went into "big boys" bed he refuses to sleep under the duvet. It has to be folded neatly at the foot of the bed, and he either sleeps in grobag or sometimes fleecy all-in-one suit. wakes alot in night i'm sure he's cold so have put loads of clothes on under fleece suit, and he slept better (although still woke few times (sad)!). ANy thoughts or suggestions from all you wise folk out there?
