Do children grow faster in the spring? Should I give my child a calcium supplement?

There are indeed studies that show that children may grow taller in the spring and summer months. In a 1994 study [1], Swedish researchers followed 50 prepubescent children, measuring height every 4 weeks and calf length every 1-2 weeks, and found that the average monthly height growth rate was 5.06 cm/year in the fall and 8.15 cm/year in the spring, while the calf growth rate was 1.8 cm/year in the fall and 2.63 cm/year in the spring.
