On which pages does Auggie talk about his favorite helmet?

When I was little, I used to wear an astronaut helmet everywhere I went. pg. 58

Sometimes I wish I could still get away with wearing that old astronaut helmet I used to wear when I was little. Believe it or not, people would think seeing a kid in an astronaut helmet was a lot less weird than seeing my face. pg. 159

"Dad, I loved that helmet! It meant a lot to me! I was bummed beyond belief when it got lost—don't you remember? pg. 202
