We recently measured Grace's height and it is about 94cm. When she was born she was 47cm…..which means that she has doubled in length since she was born, in 2 years and 9 months. We measured her height at 2 years as 88cm, which supposedly means she will be 176cm tall when fully grown. Although her first doubling was quick, her next (roughly) is going to take 10-15 years.
