I always wear a helmet and insist that my kids do too. But, I know that's kind of a cultural thing. There are plenty of places where it's wierd to wear one, and that's ok. Around here, it's wierd to not wear one. Although I posted that when I saw the photo and read the title my first impressions was one of "I would never . . . . ". That's me. The OP lives in a different place. She is doing what is "normal" for her area. If we want to suggest a different view of the scene, we should leave it at that . . . A suggestion.
I doubt she is any less loving of her son than those that have already posted, and nothing is more insulting to a mother than to suggest that she does not care enough about her children.
