Here goes, I'm concerned my friends children are really overweight. The 7 year old wears age 13 school shirts and cannot fasten the top buttons at the neck as it's still too tight. Their mother says that he is "big boned". Both of the chikdren are tall for their age , however they have pot bellies and rolls of fat on their backs and the boy walks oddly as if it is uncomfortable for him. I don't know what to do as being British I dont wish to offend! The parents are tall and heavy set, but her sisters of a similar build have slim children. The eating habits are awful -kebabs and pizza all adult portions and my daughter was eating a nectarine and neither of them knew what a nectarine was?! Should I broach the subject or will the school take action?
