My Dd 12 is overweight. She has been for the last 2 years. She is very active, sport 3 times a week and walks to and walks 3 miles a day. She eats quite healthily at home, the same as her brother who is bang in the middle of the healthy weight section. She does buy snacks at school despite my best efforts and goes to Starbucks on a weekend. We have talked about healthy choices etc. I try not to buy snacks in but obviously have some over Christmas. I do bake healthier snacks so she's not deprived. I understand a bit of weight gain is normal during puberty but she got a letter in year 6 flagging she was overweight. I spoke to the school nurse then who said she would monitor it without drawing any attention but it was a busy year and I didn't hear back. I weighed and measured her myself for the first time in over a year today at her request ( part of a am I as tall as you yet? ). I was really shocked. She is heavier than me and 2 cm shorter. Her BMI puts her in the very overweight section. What can I do? Should I do anything? Her weight doesn't bother her. She's not aware. I don't want to trigger any eating disorders etc but I also am following all the advice. She's active, eats well, sleeps well etc and I don't understand why she is the size she is. She wears size 12 adults clothes and is 5 ft 4 and over 10 and a half stone. Any advice would be really appreciated.
