I had a mom tell me that she didn't want her daughter napping anymore because it was ruining bedtime. I was like you, said sure that's fine. It wasn't a big deal to have her up as she was really good about watching tv, reading, doing puzzles, workbooks and being quiet. I re-did my contract in January and switched it to every child needs to lay down for 30 minutes to give me a break. If they are still awake after that than they can get up and come upstairs with me. Mom was fine with this and just asked that I let her know the days her daughter had a nap. She usually napped 30-60 minutes and mom just pushed bedtime back on those days. Tomorrow is their last day as she is going to full time preschool and she won't be having naps anymore anyways because preschool is in the afternoon's.
