For those that judge, please, please don't. Often its not silent, you may comment to another adult or even to the overweight child, I know my poor ds has had it for years and it has broken my heart many a time.
I have 2 DC's. Both have been raised the same, and given the same food. My eldest is petite and slim, could eat a horse and doesn't seem to put weight on.
Younger DC just turned 17. Was on the 99th percentile for height and weight since birth. He is about 6'2 now and in an adult large to x large. He has been an extremely picky eater since about age 10, however this does not equate to him living off junk food as I expect people have wrongly assumed.
Never forget the day he came home and told me an adult called him a 'Fat Bastard' and the tears that followed. Or the time when we were in a 5* AI when he was 13 and an adult called him a 'Fat Pig' when he was swimming in the pool with a t-shirt as he was embarrassed about his weight.
Before anyone asks what I have done about it over the years? Everything. Regular swimming, bike rides, calorie counted for him, 2hr walks on mild evenings, home gym etc.
Food through his childhood very normal, mostly home cooked. The closest I ever got to 'junk' food was/is frozen pizzas or breaded chicken.
Today for example he had an iced coffee before College (not great, but he doesn't do breakfast atm!) He took in a ready made pasta salad to have for lunch, 1X low calorie crisps and 1lt of water. He has come home and I am cooking spicy chicken with a Jacket Pot and a mixed salad. He might have a bowl of 'Pudding Cereal' prior to bed.
Not the diet of a fat bastard, a neglectful mother or a multitude of other insults I have heard over the years.
Plus side, he has had a good bunch of mates since primary that seem to love him, always someone popping over to see him and a good social life. He doesnt need to be reminded or judged by strangers he is overweight. He knows. He's trying.
