Just after Xmas we noticed that my eldest was getting on the chubby side so had a chat with him, explained it was nothing to get het up about but just to rein in the eating crap (he'd been stocking up on shit after school), and within a few weeks he was back to normal.
That's one of the most sensible things I've read in a long while.
I'm tired of reading people saying you should never mention a child's weight to them, in case it gives them an eating disorder.
I think it's nonsense. If we stop making weight a taboo subject and just treat it like any other natural part of life (which gaining/losing weight is), then hopefully children will learn to take responsibility once they're old enough to buy junk food etc, or stop taking as much exercise as they used to.
There are fully grown adults who still blame their own weight on being told they were overweight children...but how many future adults will blame it on not being told they were eating too much crap and taking too little exercise?
Once upon a time, parents would never discuss sex or drugs with their children in every day conversation...but thankfully that seems to be a more open subject in most families.
I'm hoping weight gain/loss/diet etc will become more open too in the future. It shouldn't have to be a difficult conversation imo.
