I'm just wondering how much sleep is normal as I think my DD 21months is sleeping too much in the day. She has a nap usually after her lunch, I usually get her up after about 2 and 1/2 hrs but she will sleep for a lot longer than this if i leave her. She sleeps fine on a night 7.30 to 7.30 and doesn't wake in the night. When she is at nursery she is sleeping for about 2 hrs which I think is probably due to the noise and too much going on around her. She is a good eater and is in 98th centile for height and weight so I think she's growing ok, just feel a bit worried!!!
