DD2 has not been a good sleeper in the day so far but things seem to be getting worse. She only sleeps for about 20mins / half an hour whether at home or on the go and if she is put down at any point she wakes up almost immediately. Frighteningly the sling seems to have lost its magic too. As a result she is always tired during the day and we spend a large part of it trying to get her to drop off which is a bit unfair on DD2 who is 2.4.
Any thoughts on how we can get her to sleep for longer during the day? Or is this just her? Or is it 4 month regression?
