I believe you will find that in a few weeks his schedule will change drastically. He will miss you as much as you miss him. So he will not want to go to sleep when he just now has you after being away from you all day. He'll start staying up later a little bit each night. His naps will probably be a little longer during the day.
It will all work out :) You may want to play with the schedule between you and the provider. But every time you think you have a good schedule, he'll change it up on you. I always think it's so funny when mothers of children that are less than one year old will talk about their babies sleep patterns like they've been doing this or that for so long. So long? They've barely been a live but a few months. The first year most babies will change their routines a dozen times over and every few weeks.
