I picked this book up first because my daughter LOVES Berenstain Bears and second because I love all books that are disability inclusive. Though the language is somewhat outdated now (it was written about 30 years ago, and a LOT has changed in the disability community since then), but it does do a great job describing the typical reaction an individual with a physical disability has to the over-nice, over-help they sometimes get.
My favorite part was:
"Suppose everyone kept reminding you about something you can't do very well... like math," said Mama.
"But I'm good at all kinds of things!" cried Sister. "Science, English, History, baseball, hopscotch, jump rope, roller-skating, dancing!... It wouldn't be fair if people kept reminding me about math!"
Mama smiled. "Exactly," she said.
"Exactly what?" asked Sister. "What's it have to do with Harry McGill?"
"It has everything to do with Harry McGill," said Mama. "Everyone must do that very thing to him all the time. When they meet him for the first time, they ask or say something about the most obvious thing he can't do- walk. And they probably don't give a moment's thought to the things he can do."
Another part I liked:
"Forget about Too-Tall and the gang," Brother told Harry one day at recess, after a morning of the gang's teasing. "They just don't realize that everybody's got a handicap, even them."
"How do you mean?" asked Harry.
"My papa has a hard time explaining homework problems to Sister and see," said Brother. "Teacher Bob has trouble with computers. Sister has to study extra hard to do well in math. Freddy's no good at sports. And I am a klutzy dancer. Our handicaps just aren't as easy to spot as yours."
