I’ve made an effort to buy my nephew toys that aren’t too gendered, blocks, playdo, stuffed animals, etc. The only one that I’ve bought him that is explicitly marketed for boys I would also have bought for a niece, it’s a shape and color learning toy that looks like a car that you “fix” with a little wrench and screwdriver (my dad is a mechanic so it’s a “fix cars with Poppa” toy not a “you are a boy and should like cars” toy). Should me brother and his wife have a girl at some point I plan on giving her art supplies, legos, and science kits just like I will for my nephew.
