The ABC 123 program through Auburn parks and rec still has a few slots open. They told me people could still register their children (ages 3-5, must be potty trained) through the end of this week. I've had children in this program many times and really liked it. It's also really cheap!
Check out the parks and rec brochure for more details and go over to Dean Road Rec Center if you want to sign your little ones up.
