Dilemma

I'm mulling this over, and I could use some advice.

I stay at home, but Ian goes to preschool 3 mornings a week. Chase stays with me all day.

Chase has always been a really social little kid. He wants to be where the action is. He follows Ian around all over, he follows me all over. I watched Tiff's kids yesterday (4 of them) and Chasey was all about being part of the group. He sat and listened to stories as Kenna read, he went down the slide with everyone, he even tried to participate in a game of "chase Ian around the house screaming and running". He just likes to be around other little kids.

So, do I explore the possibility of putting him in pre-preschool 2 mornings a week at Ian's school? Is that weird, that I stay at home, but ship my kids off to school in the mornings? Doubly weird, I watch another little boy, so I would be staying at home with a kid that is not mine, so that I could pay for school for both of my kids...?

I just don't know if it's worth it at this point...would he get much out of being away from me 6 hours a week at this age? Or would it be more practical to wait until next school year when he is walking (like the rest of his class will be). Or would this be the motivation that he needs to practice more gross motor skills as he watches other little kids doing it or tries to keep up with everyone?

I just don't really know what to do.
