Mac does this, but I find it takes it's toll on him after a few days and we do a catch up sleep day once a week or so.

For these days all I do for his is feed, change, sleep. I don't talk to him or interact with him in any way other than cuddles if he cries too much.

 I do find I have to do this once or twice a day normally anyway and he usually cries himself to sleep.

I would say if she isn't crying and just lays awake in her bed, then put her to bed and leave her there. She'll eventually fall asleep and if she doesn't cry then she's obviously not distressed. But if she's sleeping so well at night maybe it's because by the end of the day she's exhausted from being awake all day.

Oh and Mamma2N's suggestion about wearing her is also a good idea. I have done this a few times with Mac, mainly if we are out places and he won't sleep on his car seat or pram. He sleeps in his Moby Wrap no problems.
