When I were a lad and for our kids it was always a case of "you get what you're given".
OK there were/are certain foods that individuals can't stand eg my daughter has never been able to eat mushrooms but apart from that we ate what was on the plate.
That was the same for me as a kid. Totally counterproductive. It gave me hang ups about food that took decades to get over. I was 30 before I‘d touch any veg, and now I’ll eat most of it. Except peas, even the smell of them cooking makes me lose any appetite. Apparently i spat them out when I was a baby!
Anyway I swore I wouldn’t subject my kids to that and I haven’t, and they’ve turned out fine. Quite adventurous if anything, even no. 2 son who has sensory issues.
