It's very hot here at the moment, I've got her in a vest and a thin sleeping bag, but when she has bare feet she somehow kicks so that he gradually walks up the inside of the sleeping bag and ends up all bunched up. Socks won't stay on, it's too hot for them, and also I don't want to restrict her circulation at night. Nobody seems to have mentioned this problem so what am I doing wrong? She's 5 months if it makes a difference. Thank you!
