Grandaughter Knitting

Tonight we baby sat three of our grandchildren. When they arrived our 8 year old grand daughter asked me to teach her how to knit. She caught on right away and after about 1/2 hour had one inch of very neat, even stitches. Is it in her genes that she learned so fast or is it left over from the times she sat on my lap at about a year old and held the needles along with me?
