Dd2 (10 weeks ) is a brilliant night sleeper but her day naps have gone to pot in the last two weeks. She's literally doing 45 mins 3 or 4 times a day but does sleep 12 hours at night.
It seems the room not in almost darkness is the problem. With dd1 out of sheer desperation I put black bin bags on our bedroom window as it's very big and none of the blackout blinds would fit.
Am l going to have to do the same again (what will the neighbours think!)
