I was just thinking about this.
Passed a mother and her two kids - about 10 & 13, I'd say - on my way into town.
Both kids were overweight; no doubt about it. Round faces, filling out their clothes. Not rolls of fat-type overweight, but carrying too much weight spread over their bodies. They looked dumpy, despite both being quite tall.
I only clocked them because both kids were also drinking Shakeaway milkshakes - and I was momentarily possessed by a desire for a chocolate milkshake.
What went through my mind was: I bet that mum is a great mum, a kind mum, and likes to "treat" her kids.
Trouble is, it is so much easier to "treat" your kids now than when I was little. We had sweets once a week; and even then it was a Milky-Way, or a few Rolos, or something. We just weren't exposed to them so often. Now you can't move in most towns for passing cafes with cakes, or little shops with sweets, or whatever. There's been a food-explosion since the 1980s. It is very difficult to avoid eating, I reckon. And if you need to run errands and the kids are with you, how much easier is it to say, "Look, after I've done this, we'll go for a shake".
But it's cruel, in the long run. If those kids don't drop the weight as they grow - which they might yet - they'll be miserable. It's wretched to be overweight, if you're not comfortable with it. Kids are so self-conscious. And it can be so hard to lose weight but still eat enough & the right kinds of things, if you're a teen.
