My dd (almost 11) has always been on the overweight side - she varies between slightly overweight to more so depending on growth spurts.
Obviously I am not happy about this and have posted and read many threads. We do lots of exercise including always walking to and from school, I cook healthily from scratch (am not overweight myself), I do as much as I can to counterbalance the fact that she is sedentary by nature and loathes veg (but eats a wide variety, knowingly and unknowingly).
My dh, her dad, is obese but also is big in frame and tall, ds, 8 is sturdy and solid but has never been overweight.
They are what I would call normal kids in that they love sweets and crisps etc but they do not get many of these and I am always being told by my dd that her friends think her lunchbox is really small and lacking in "treats" (pitta or two slices bread with a filling, frube or dried fruit and small biscuit/ fruit flakes/ Choc rice cake, so 3 things and I encourage her to take an apple for break. She always clears her plate, rarely leaves food (if it's something she likes) and prefers brown bread, rice and pasta to white as its more filling.
So overall I am doing as much as I can to keep her weight ok, she has no concept that she is overweight, she has great self esteem and confidence and I think that she will be genuinely shocked and upset to be told that she is overweight. While I don't want to dent that confidence she needs to take ownership and responsibility for what goes in her mouth especially when she goes to secondary next year. She would happily eat huge amounts of sweets and crisps if she was let loose and I am worried that as my input / control diminishes, her weight will go up drastically.
What to do? I'm inclined to show it to her as I'm sure she'll want to know anyway but need to be prepared to gently guide her through it.
