Something that I've been dying to say for a while, but haven't dared. Are we really sure that mentioning the 'fat' word infront of a child is really so reprehensible and will lead to eating disorders?
I'll confess, I have said to my 3 year old when she has asked for more chocolate (after polishing off a considerable amount)- to which I have replied "No" and to which she has asked "Why?"-
"Because you might get fat"
I have then qualified with - "You're not fat, you are perfect, but if you eat too much chocolate / sweets / chips you might become fat. It's better to just have a little bit of those things now and then, and mostly eat mummy's 'decent' food. That makes you healthy and strong."
My dd - although only 3, likes an explanation for everything, and I don't think it's harmful to give her the facts, as long as it's a message not too strongly / obsessively delivered (actually it should be 'matter of factly' delivered), and it is in the context of her knowing (and being told) that she is beautiful, clever, lovely etc
I know you could argue that I am teaching her that fat is wrong - I don't personally think it is, but sadly society does, and consequently she will be disadvantaged (perhaps only subtley) if she grows up fat.
