Thankfully the little ones seem to be adjusting now. The outright tantrums have stopped, though there's still a lot of sulking going on. But they seem to have accepted that they're staying with us now.
They're pretty strong, for being kids. I cried like a complete wuss when I left for college, and they were only five states away, and I was a lot older.
I just hope they'll be alright, in the end, and that we do right by them.
