That's so sweet that both your boys had meltdowns, my D9 does that too. It's a nice way to look at it, that they're having so much fun they have a hard time giving it up.
Well, as much as I'd like to think they threw tantrums on my account, they really just did not want all the fun with the games and activities to end. They're just little kids after all, and who can blame them for wanting it to continue just a little longer still. Right?
