even without the insta-aesthetic lunches though, it's clear you actually put effort into sending your kids to school with foods you know they like - you KNOW your kid doesn't like bread, so individualise his lunch to suit him. it's not about cutting sandwiches into shapes - although if that's your thing, you do that! - it's just the simple fact that you know each of your kids and cater their lunch to them and foods you know they like and will eat that makes you a good parent. if one of the Radford kids didn't like bread, Nowull wouldn't know because he wouldn't ask, and the child wouldn't get soup or any other alternative as it is far too much effort for him to break away and do something different, actually treat each child as individuals, so presumably they just go hungry it would be an interesting twist of one of the kids decided to go veggie, as guaranteed they'd still open their school lunchbox and find ham sandwiches.
also, by the sound of it, you also give your children a sufficient amount of food for lunch - not one slice of wafer thin ham whacked between two slices of bread, no butter, job done. it's hardly an adequate lunch for school kids who need energy to focus etc, and not surprising all the Radfraud kids look so malnourished. given the way they brag about having 22 kids and working hard to support them all with out benefits, and the sheer amount they spend on holidays, it's not as though they are struggling financially - they could easily afford to provide each child with a decent packed lunch, based on their individual preferences.
but as with everything, Sue and Noel know nothing about each child as an individual - as proven by Sue's inability to buy her kids clothes that actually fit them, and some of the kids being disappointed with their advent calendars because Sue had simply assumed kids of similar ages would like the same things, and didn't actually bother ASKING which advent calendar they would like. because y'know, asking the kids which sandwich fillings they prefer would involve actually interacting with them and then remembering one single fact about each of them as individuals - Sue is far too busy spending money and planning holidays to bother showing any interest in her kids. guaranteed that neither Nowull or Sue could name a single one fo any of their kid's friends - if they were asked, they would simply list the few Radfraud siblings closest in age to them.
