Any mama's with their 2yr registering for preschool this fall?

Our son's going to be 2yrs old may 24th. we see how well he's adjusted to toddler nursery 1x week for 1.5hrs in the last couple months, before he'd be home with me nearly 24/7. His eagerness to learn is fun to see, so we decided to register this fall for T/Th 3hrs each day, seeing that he's got the letters, numbers shapes, colors down... we think it will be beneficial though I'll miss having our times together... but I'm ready to adjust, now being prego with # 2. any other mama's doing this?
