Hi, my 11 week old daughter naps once during the day but for 3 hours. Usually between 1-4pm and her bedtime is 8pm. She wakes at 3am for a feed and change and wakes for the day about 8-9am. She feeds well, is approx 11lbs and had plenty of wet/dirty nappies. I've read that babies should have wake windows of approx an hour at this age.... my baby could nap in the morning if she wanted to but doesn't.... is this normal? Thanks
