These points on diet are really good too. I spent quite a lot of time with my grandmother when I was growing up and as she’d come from a very poor background her approach to food was quite no-nonsense. She would expect me to finish everything that was on my plate but she wasn’t in the habit of giving me that much. Also if I was adamant I didn’t want what was being offered or didn’t need it her response was “okay, the next meal is breakfast, you sure you’re done?” and if I said yes that was the end of it. My mother followed a similar approach and I’ve grown up with a very laid back approach to eating (both variety and amounts).
Contrast this to my two younger brothers who have been brought up with a dinner routine I wouldn’t wish on anyone - elbows off the table, no talking, no TV, we’re having a NICE FAMILY DINNER DAMN IT!, one of them being yelled at to speed up, the other to slow down, one being told to eat more because he’s too thin etc. It’s one of the least fun experiences I’ve had eating dinner with my father and his family, and funnily enough I’ve never had any problems with dinner times when I’ve looked after them and prepared/served dinner when I take the same relaxed approach to food that I was raised on.
One of the themes running through any child with an eating issue in the parenting programs I watch is how stressful meal times are for everyone involved because the parents are obsessing with what/how much is being eaten and when etc, and how it just makes the process harder, not easier. Children don’t let themselves starve, as long as you’re making the food available they’re not going to drop dead of hunger because you didn’t force them to eat.
