Baby’s nearly one year old now. We’ve worked out how to weight her but nurse and still have trouble measuring her height. She just will not stand up straight against our measuring çhart. In fact she can’t stand up all yet! So we measure her upside down, Last year nurse her Baby’s feet, keeping them level with the 140 cm mark, while I read off the mark level with the top of Baby’s head: 97 cm. This year it was my turn to hold the feet. Being taller than the nurse, I held them against the 150 cm mark, while nurse crawled on the floor to read the mark level with the top of Baby’s head: 84 cm. How many centimeters has Baby grown in her first year?
