I do have younger sisters but not in the age range you need.. they’re either already in the parsha, or they have a while to go!
Unfortunately, though, it shouldn’t be such a rarity that people think this way. You want to raise kids that think of others before themselves.
And mepal, most of my family does think this way 🙂 (though I don’t know if they are as strong about it as I am)
