Well, needless to say, it turned out to NOT be a problem.
When I came to pick Axel up on the first day, I spotted him running around and laughing with the other kids. When he finally saw me, he ran up to me smiling, gave me a big hug, and then ran back to the playground saying "One more minute". I let him go, but then he wouldn't come back, so eventually had to drag him to the car crying "more school, more school!" Good thing he is going to be there every day!
