Kevin was only six and in the first grade and was made much over by everyone. […] Claudia also thought that he was terribly babied and impossibly spoiled. (1.13)
There's a lot of talk about age in From The Mixed-Up Files, and we see that when Claudia talks about her little brother Kevin, who is terribly immature for his age. We mean, he's only six, but seriously Kevin… get your act together.

Saturday seemed a good day for housekeeping chores. There would be no school groups for them to join. (5.2)
Even though Claudia and Jamie are just kids (after all, they fit in with those school groups just fine), when they run away, they have to take on some pretty adult responsibilities. Like laundry.

"Well, the summer before last, I had just finished the second half of first grade."
"So boloney! It was all I could do to sound out the name of Dick and Jane's dog." (5.49-51)
Claudia needs a reminder that people change as they grow older. Jamie wasn't always as financially sound as he is today, and he certainly wasn't smart enough to read a whole book about Michelangelo.
