well in my opinion i would say you need to make her take a nap alot sooner then she is and only let her sleep for about an hour and for a while she is going to be crabby but she will get use to it. also that is the babysitters job so if its hard she needs to deal with it that is her job. my son use to be the same way till i was like enough is enough and im a stay at home mom so i just changed the way he took his naps and dealt with the crabbyness. it only lasted about a week. hope you get some good advice.
