Mack has started going to a little class called Pregroupies at Frolic and it's a pre preschool. It's basically something to keep your 2 year old, and yourself, from climbing the walls. Surprisingly Mack is an amazingly well behaved, friendly, generous, focused student. There are 5 kids and 2 teachers so he gets lot of attention, which helps, but I think he likes the pace of school. He's my favorite kid in the class.
