"The one my Pedi described was to measure the child at 2 y.o. (2y6M?), double that for a prediction, +/- 2" of the child's adult height. I think the two different ages were supposed to be one for girls and the other for boys but I can't remember which is which. What do you think of this predictor tool?" I think you need to weight until 2 years old to use it. The formaul I posted is int he Harreit Lane handbook. Id have to check for the original reference Rob *********************************************** The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(TM) mailer for lightning fast mail delivery.
