Oh I hope the other poster who was asking why her proivder has a rule about not dropping off between 11 and 3:15, reads this post! This is EXACTLY the problem with naptime drop-offs! So she is dropped off either right at naptime or after it has begun...no time to settle in, play with the other kids before going to bed. Also she may have napped already at home in the morning...there is NO routine! Kids love routine! I don't know actually how much success you will have with this if the parents are not willing to work with you on the routine. I would let her cry...but then if she has slept already in the morning, that is not fair to her as she isn't even tired. For me, the only solution would be ot have her dropped off much earlier in the day so she has the morning with you and is good and tired for naptime.
