Hiya Hunnybunny,
Don't get me started on health visitors, I have had more arguments with them over my dd. I'm not saying that all health visitors are the same, I just don't feel I have good ones at my surgery.
I was told EXACTLY the same as you, at 12 months my daughter was quite a bit over the percentile for both height and weight. They said that I had to stop feeding her too much - puuuurlease.
The thing is her daddy is 6ft 4" and I'm 5ft 11" so she was bound to be tall, she is now 5 and doing very very well at school, she is one of the tallest in her year, but then again so was I, she is excelling at ballet and PE, so in my experience the health visitors comments were totally unfounded.
My second dd who is nearly 3 is going the same way, she is in clothing for 4-5 years old, purely for her height and clothes have to be taken in at the waist.
Please don't worry, if you would like to talk please contact me through CAT.
