i am 5.11 tall, and was without exception the tallest child in my class for most of my school career. i was extremely self conscious.
my mother did actually take me to see a doctor when i was little and as i was in proportion nothing was wrong.
my mother is only slightly above average height herself, and although she tried to advise on how to cope with the teasing she didn't have that much of an understanding of the situation. her main piece of advice was to counter comments about my height with a smart remark back. unfortunately this only left me feeling my height was something to get defensive about.
so from an insider's point of view here are my top tips!
When people comment on your daughters height, treat their remark as a compliment. "Yes, she's tall, isn't she lucky!". People aren't always trying to hurt her feelings with their comments, some people are genuinely admiring, others just never learned not to make personal comments about other people's appearance.
Help her to see that her height is a fact about her, it cannot be changed she has to accept it. People are all different, some fat/thin/blonde/dark etc etc etc.
Above all, boost her confidence in other areas of her life. She WILL have comments made to her by her peers but if she can manage to take it at face value she will be fine!
When she gets older she will realise how wonderful it is to be tall. It's just really sucks when you are a child, that's all!
Of course my own daughter is tall. (my dh is over 6ft) She will be 3 in August and is 100cm tall.
I'm doing all I can to ensure it doesn't take her until she's 20 years old to see her height as the asset it is. That's about how long it took me.
ps) i would get very shirty with the nursery staff if i were you. how dare they suggest your dd should go to a doctor. i'm sure there are a few overweight children in her class, i'll bet they wouldn't dare suggest to the mothers of those children something might be irregular there.
help your dd work on her confidence, i feel sad that she's stooping already and is only in nursery.
