I don't have anything in my contract about naptime but I agree with you. I've just started with these parents so I'm not sure how to go about this. She did say if the child is really cranky to put her back down. Maybe I'll try it for a week knowing that it won't go well, and then after that week I'll tell her it did not go well and so I'm am letting her nap as long as she likes and also let her know that I am going to be revising the contract. I have put in the contract that revisions may be made. Hope that goes over well!
