If it were me, I would just plan what works for your schedule and assume your kid will make friends/see their school friends outside of camp.
That being said, I think it’s too early to coordinate with school friends. IME with young kids, friendships can change a lot over the course of the year, and you don’t want to be stuck with plans all summer with a kid that your kid had a falling out with. If coordinating with others is a must, do so with the daycare friends.
