Do some people grow in bursts?

Question:

Minister,

I have a growth pattern where every time I have a birthday, I am at the average height for my age. Months later, I always grow 2 inches above average. Some people are telling me I grow in bursts instead of steadily, and my growth will be extended. Is this true?

Answer:

Actually, most people grow in bursts. Some grow in a few bursts and shoot up quickly; others have more frequent bursts and grow more steadily. Measuring once a year or once every six months averages out the changes.
