A Chapter Ending

The best part about a chapter ending is that there's usually another one after it. This is definitely the case in the chapter ending today.
Tonight, my baby graduates preschool.
My husband just rolls his eyes and comments about how he can't figure out why we need graduations before high school. And I really didn't think I was going to be emotional about it.
​But he's my baby. My last one to finish preschool and move on up to "real" school.

I know he's ready. Already picking out words, doing simple math, and wanting to know all about what it's like in Kindergarten from his sister who was there last year. That's not the issue.
I think what's getting to me is that I've had him as my constant sidekick and shadow for five years now. And next year, I'm going to have five days a week where he's gone most of the day. Part of me is elated at how much I might accomplish. The other part of me wonders if it's going to be a bit lonely.
But, no matter what, this chapter is over. He'll be on stage tonight singing about how he's going to kindergarten and how Jesus loves him. And he'll wear that light blue cap and gown. And eat cookies.
And then, in a few months, I'll take him to school with his sister.
Maybe this will give me more time to write? Ha!
Any tips for surviving all these chapter endings that seem to happen at once?
