Hi, can anyone tell me how much day sleep a 13M needs? My daughter has between 2-3hrs between 2 naps normally but the less she has the better she goes down at night? She only had 30mins on Xmas day and went down a dream and slept till 7:30! Bedtime is currently a battle..her first nap is usually around 9:30. Does this need to be a catnap? Thanks
