I suspect if you give your children their own growing area the problem might heal itself. I did this with kids in school a few years ago, the gentle rule was" if you grow it, you eat it". We had non veggie kids eating all sorts of stuff, the really fun thing was listening to them verbally selling the idea of their veg to another kid who wasn't keen. Priceless..
Still say Charlotte, supposed to be second early but we grew it as a first and then left some to grow om, they actually grew quite large.
When you get your kids spud hooked don't forget the old wisdom" you can eat as many as you like,but you scrape your own".
Have fun
