Hi, after a bit of advice. My 17 month old has always slept well in sleeping bags but she has recently started unzipping the bag just after I put her to bed to the point that yesterday it was just hanging round her neck and clearly not safe. So I’m thinking of introducing a duvet especially as it’s warmer and won’t matter if she isn’t under it all night. However at the moment she moves all over the cot, literally doing 360 degree turns.. how can I help her adjust? Thank you
