YABU. And it's good to see that the majority of people think that.
She is only a very young child, but you REALLY should have said to your daughter, 'please do not comment on peoples looks like that!' And then said sorry to the lady. You were very much in the wrong for not doing that.
Calling your child 'it' was a bit off, but if your DD is old enough (and intelligent enough) to make the observation that a lady is 'big' (very loudly in public,) then she is old enough to be called out on it.
And your DD did mean fat, and as some posters have said, it's very hurtful and upsetting to have it pointed out when you are overweight. So the woman was probably just snapping as she was angry at the comment. Someone said the little girl was just 'making an observation.' I am willing to bet that she wouldn't make a point of commenting on someone's appearance if they were slim.
I also agree with the poster saying people are wrong to say 'we ALL comment on peoples appearances!' Speak for yourself! I don't go around pointing at people and making comments about their appearance. Speaks volumes about some of the people on here that they do that!
And finally, people need to stop assuming that everyone's kids have said 'rude' things to people. Mine never bloody did. And if they had, I would instantly have scolded them for it, and apologised to the person they insulted.
