I've read that if you measure a child when he is two and double the measurement, you should be able to tell how tall he/she will be when they are an adult.
Saturday was my youngest son's (Ethan) birthday. About two months ago, I measured him. He was about 34" tall. People have told me how big he looks.
But his older brother, who is now 4, was 35 1/4" when he was two. I told my wife then, Cayden will be bigger. No way Ethan will grow that much in two months.
Well, I just measured the big boy. 36 1/2"! He grew over two inches in two months!!
I'm going to have two 6 foot boys. Can you imagine our food bill?
