Rarelondon I just wanted to say that your thread has really struck a chord with me. I have a very overweight 11 year old (150cm and 9st 12). He is also T1 diabetic, not I hasten to add because of his weight - T1 is an autoimmune condition - but the insulin he has to take can cause weight gain.
Since his diagnosis at the age of 5 his weight gain has consistently outstripped that of his height. We and his consultant and dietitian, have worked really hard to avoid this but it has happened nonetheless. His 14 year old brother, same family diet (healthy, home cooked, lowish carb, lots of veg, no biscuits, cakes on birthdays etc...) is and always has been a stick. I have been at my wits end. Ds2 is averagely active, enjoys TV and X-box but we have a dog and do lots of family walks and bike-rides. Some of his friends on the other hand are far less active, eat crisps, choc, sweets ad hoc and are literally half the size. It is very upsetting.
I don't have a solution, I wish I did. Short of turning our home into a boot camp for DS2 I don't know what more we can do.
What I really wanted to say is just love her. And don't be judged by people who will try to say it's your lifestyle, portion sizes, parenting etc. Sometimes, just sometimes, it isn't.
