Do sleeping bags stop babies from turning over at night? Do they get frustrated when they can't move about? My dd had a Grobag till she was 9 months old but once she started turning over I was worried it would hamper her movements too much. Now she turns over all the time and keeps throwing off her bedclothes and as her room is quite chilly at night I would like to put her in a bag again but am worried she will feel too constrained. Hope this makes sense. Any advice?
