Dear Prudence,
I have a 5-year-old nephew whom I adore. However, my younger brother has very specific ideas on what boys can do and has directed his son’s behavior accordingly. My nephew used to adore watching “magic girl” cartoons with my daughter and would ask to buy the pink toy cars at the mall. Now, when his father’s around, he won’t even touch pink markers. I had to interfere when he hit one of his friends, then broke down crying, because she wanted to play Barbies with him. I don’t know how to broach the subject with my brother, and I know if I so much as bought my nephew a pink toy, my brother would perceive it as deliberately undermining his parenting. Do I have any right to address this issue, or would stepping in at all be too invasive?
