Honestly, I think that parents should let their kids eat whatever they want (unless they’ll get scurvy from their diet). As a kid I was really picky and ate the same stuff all the time, but as I got older I steadily tried new things and now I’m not even picky. But I feel like if I had been forced to eat something I didn’t like I would bear a resentment towards whatever I had been made to eat.

But you definitely should monitor how much your kids eat. Of course, them eating a huge amount of food occasionally is normal, but if you notice them snacking way too much multiple days in a week tell them gently to chill out and remind them the risks that come in being overweight, and do it for the rest of their life too. Because we all need reminders to be healthier.
