Opinion on cross-feeding children or multiple breastmilk supplies?

Hey everyone to make this short, breastmilk I've cooked with and used for many years in my whole family. Every recipe and cereal is usually breastmilk of mine. I've also been a huge supporter of cross feeding or letting multiple people breastfed a child. My friends have not often but sometimes breastfed kids I have or I've even breastfed my niece when she was sick for months.

What's y'all's opinion on it? Y'all think we all are weird or are people not speaking up about this?
