maybe she hadn't really learned to 'self settle' and was just zonked Like Krysalyss said, she might be extending the time she wants to be awake. With DS at 6 months, even though he can go four + hours without a nap in the middle of the day still only lasts an hour and a half first thing in the morning. I'm quickly figuring out that as soon as I get used to whatever it is he's doing, he'll go and change it up to surprise me Some gentle time in a carrier or in the pram to encourage a nap if she needs it might help, or going outside to look at things to 'extend' the time she is awake, so she'll sleep for longer might also help? They're just suggestions, what works for DS. I say that as he's in bed, in dire need of a nap and is chatting away to whoever it is that he talks to when he's falling asleep! I wish they'd let him just go to sleep!
