Ok, so here's the update:
Friday morning she fell asleep quicker when I put her down first thing in the morning. Grandpa called and picked her up at 1:30 so no afternoon nap. I think this is common. I don't think they cater much to her routine, I'm pretty sure they let her decide nap time and bed time and when it's convenient for them.
So all week I have been putting her down as soon as she gets here. Some days she sleeps for 2 1/2 hours some days only 1 hour. She is still EXHAUSTED! She can't make it to afternoon nap at 12:30. But then she only sleeps 1 hour. Then wakes up exhausted still. This little girl just doesn't want to sleep. Monday Tuesday she was much better. Much less hitting. Wednesday she was terrible, back to hitting, making herself vomit. Today she only slept 1 hour so I know she's going to be grumpy!
I'm having a hard time with the routine. She goes to sleep when she gets here which is when my 2 wake up. Trying to keep them quiet is never easy. So I feed my kids breakfast, she wakes up, I feed her breakfast which is the same time my LO goes back to sleep for 45 mins. Then they have snack when she wakes up. By this time DC girl is so ready to go back to sleep but it's time for a walk, then lunch. I guess I could put her back to sleep instead of the walk but then she's up in time for my 2 to go down for afternoon nap. This leaves me NO time at all to myself. I can't see myself continuing this way, especially since I start at 6!
Please, any suggestions!
My trial period ends tomorrow but I REALLY don't want to leave the parents stranded especially because she is getting a little less aggressive. I just want her to sleep!
