Hmmm any study I have read would disagree with this nap schedule that the parent wants for their child. Most every study recommends that children never sleep beyond 3 pm or else they will ruin their bedtime.

I think if the parents is determined that it MUST be the schedule she wants i.e nap at 2 pm for afternoon then she should find a live in or live out nanny where it is 1 on 1. She wants individualized care and that is not possible in a group setting

You can't have two separate nap schedules or else there will NEVER be time to go outside and lunches and snacks are all thrown out of whack because someone is basically sleeping for a large chunk of the day in the house (either the 1 child or the other 3) when you add up the 'sleeping time' between both groups it would be totally paralyzing the provider to accommodate such a long period of naps for two different groups
