All Aboard the Kindergarten Train!!!

The title of this post, all cutesy and positive also reflects a strong feeling of moving ahead, whether I like it or not. The train is now leaving the station, will I put my kids on it or will I be seized by my underlying urge to pack the family into the minivan and escape the seemingly unavoidable task of Letting Them Go?
I know they are ready (as ready as anyone ever was).
I know I am ready (as ready as anyone can be).
This is the custom, right?

Today is what the school calls the girls' "staggered start." They go for an hour and fifteen minutes only along with a handful of other kids and they get to play and visit and have a little walk around the school and then we pick them up. Friday is the first full day - six hours. Then next week its six hours, five days a week. That means that without exaggeration, I will have more "childcare" in one week than I have had in the last 6 months, maybe more.
I don't want to give the impression I am suffering from this. Well, okay, maybe I am just a little traumatized, but it's not like I have spent the last year begging the heavens for MORE time with my girls. My patience is tested. My nerves are ragged. My body is crying out for exercise and my brain is too. Without employing my powers of spin, I can still see kindergarten as a magnificent gift to me and the kiddos. I'm just getting cold feet a little bit.
I tell myself everything will be better: I'll be able to get all that boring stuff done during the day and then when the kids come home it will be fun, fun, fun! I'll never get grumpy or anything because I will have spent the day doing yoga and baking cupcakes, right?
Honestly, I can't even tell if I'm joking.
What I do know is that rarely, if ever, do things go entirely as expected. I guess my first task is to regain my footing because I want to step deliberately through this section of wilderness.

PS: Will do my utmost to put some pictures up very, very soon.
