Bonnie,
My husband and I are the same size as you and your husband. My oldest 2 daughters are 15 (non cah and 5’3") and 14 (cah and 5’8"). They were both in the 95th percentile for height as young children. If you remember (I think we already discussed this), my cah daughter was on lupron & growth hormone for a couple of years.
My 15 year old got her period early (11.5 years) and I think that is why she is only 5’3". I think it’s just a hereditary thing (hubby’s side). I didn’t get mine until I was 15. :)
I don’t think the doctors are ever sure about height predictions. It’s all in the hands of mother nature!!! I can’t wait to see how tall my 5 & 6 year old daughters get to be (both non-cah).
