A weight and age is meaningless without a height.
2 hours a week activity is useless.
Children should be permanently active, apart from when at their desks at school.
Mine certainly were.
If it's the BMI that's 94%, that means that 93% of children her age are slimmer. Safe to say she's fat/obese/overweight.
Portion sizes, butter, salt, fats, processed crap (chicken nuggets, sausages, pies etc.) need to go. Chips have to be the work of the devil. Likewise things like mayonnaise, cheese, massive bowls of sugary cereals, crisps, icecream, chocolate, biscuits etc.
Try grilling salmon fillets or roasting a chicken fillet. Eat with a salad with a vinaigrette dressing, or maybe some green beans or something.
I'm always shocked at what some parents feed their kids. Nearly always, parents on the school run home have a child in a buggy chomping into a packet of crisps.
Yes, there are too many fat kids. You're setting them up for a lifetime of obesity and unhappiness.
Sort it. OP - are you overweight yourself?
