I can sometimes accommodate a parents request but this is too much of a change and I wouldn't agree to it. Lunch and nap are a pretty big part of the day and I schedule it around the needs of the majority of the group. 11am nap is just too early for us. We eat anywhere from 1130-12 (usually closer to noon) and they are in bed between 1230/1245 with the occasional late nap starting at 1 if we've gone on a field trip that day.

How old is he and what time is bedtime? Maybe she needs to push it back a half hour or find some way to tire him out in the evenings?
