I have a little guy that consistently doesn't sleep well at night ( 15 months now ) I started him at just shy of 12 months. He was consistently getting a morning nap, but still would not sleep well in the afternoon. I started by giving him a 30 min at 8:30 - 9 And not letting him sleep past 9:30. Nothing changed for the afternoon. So, some mornings I just pushed through and didn't give him an am nap. ( I prefer to just have them on one nap anyways ) He would crawl up on me some mornings an dput himself to sleep for 15 min. LOL

Eventually the am nap wouldn't work and the pm nap was a nightmare so I buckled down and forced him on my schedule. It was a rough 8 weeks. I'm put him down with everyone else at noon and no matter how much crying he did, he didn't get out until 2:30 at the earliest.

Now... so many months later he actually sleeps for almost 3 hours. He fusses a bit in the middle but I ignore him and leave him up and get him at 3 - 3:30 and he's a happy little man.

The key was consistently leaving him there for the amount of time I needed him up there. I put him in the quietest room.... I put fans and other noise makers on in every one elses rooms and I didn't go up for anything!

The funny part is that he doesn't nap well at all at home!

Hang in there... force her on your schedule and eventually I'm sure she'll be awesome! Stick one road and stay with it.
