Hi, my dd just turned 9 and she's exactly 5' tall, grew 5" in one year. She's the same size as her 13 yo brother, he was only 4'5 at her age. I can't believe how tall she's getting! Seems like no stopping her, and she doesn't want to because she wants to be taller than her brother :-) How's it with your kids, are they also growing so fast or are some slower like my ds? kind regards.
