I also would move morning nap up to 9-10 am even for your 10month old. This is when I do circle time and crafts with my non-morning nappers. I wake the morning nappers at 10am and we all have snack together and then we head outside to play until lunch. Everyone then goes down for nap at about 12:30/1pm for 2 1/2 -3hours. I also have early pick ups at 3:30,4:00,4:30. When the time comes to take away morning naps which really depends on the kid(13-15months I usually find) you can move afternoon naps up to 12pm if it it helps.
