You must not be a parent
All real parents know that it is pointless to serve white fish and arugula to little kids because they don’t like it, won’t eat it and will complain they are hungry.
This thread nor my comment had nothing to do with your parental choices. They had to do with charging me to buy food that kids throw away. If you like to watch your kids enjoy happy meals thats fine with me.
“I am hungry mom”
“Really? Here's some fish and veggies”
“I am not hungry anymore Mom”
‘Thats OK I will save it for you”
There's a rule of thumb I go by: if I come across something healthy that they like, I feed it to them often, and in large quantities.
For example, my boys (two sons and grandson) love my marinara pasta, which usually includes bison meat, two cans of stewed tomatoes and a large can of mushrooms. My 3 YO grandson has been eating adult size portions of my pasta for over a year.
Blueberries and raspberries are the usual breakfast for my youngest son. I just wish he'd eat a lot more, not that he doesn't eat a lot as it is. The real answer is he's too active: sports, Boy Scouts, etc.
