I would probably be moving the morning naps up for everyone including the 10 month old. Make sure if it is your own child that you are getting them up in the morning at a time that would coincide with the time the daycare kids are getting up so they are on the same daytime schedule if possible. I always started morning naps at 9 regardless of if the child was showing signs of tired. 9-10 was quiet/rest/naptime and they could stay till 10:30 if they were sleeping but no longer. Most were quite content to go back down then. If they were up too long they got over stimulated and no longer tired. They got a quick snack when they got up while the older kids did a table activity. Then we had a playtime that involved the babies making room for them on the floor. Our lesson time was during infant nap time. Then all are ready for lunch by noon. The older kids go to nap at 1 and the babies go to a play yard/exersaucer or some other confinement while I do diapers and put older kids down. Then one at a time the infants get a diaper change/quick cuddle and into bed or a diaper/bottle and into bed. That usually still gives me an hour of naptime overlap - which is all people that work get for lunch hour. The babies usually only sleep 1 1/2 hours if doing two naps so everyone is up at the same time to do snack and end of day stuff.
