My 11 month old daughter sleeps through the night from usually 7.30pm til about 8.30 am. she also has a morning nap usually of about 1 - 1/2 hours and an afternoon sleep of 2-3 hours. A total of 16 - 17 1/2 hours so she's only awake for about 7 -8 hours a day. In all other ways she is a happy active child she eats very well and has just started crawling (a little later than her counterparts) which has meant she now sleeps more than she did 2 months ago as she seems to get very tired. I know they say most babies her age sleep an average of 12 - 13 hours but she sleeps much more than that. should I be worried or should I just cheer hooray because she sleeps so well and I get free time!!!!!
