DD been in sleeping bag since 12 weeks. Wanted to try duvet/ blankets etc but uncertain how to make transitin as DD seems to move all over her bed during the night whilst in sleeping bag...thus banging her head and ending up crying. Was thinking that blanket/ duvet may help prevent her moving around so much at night and would be a first step towards her big girls bed when we can take the sides down off her cot. ? Any ideas? WOuld greatly appreciate anyones help with this.
