why do we refer to infants above a year in months?

Question

For example we refer to infants over a year as 13 months, 16 months, 24 months, etc. Is there a reason for this convention?

Answer 1

Because they change every month until two years of age. Then we start referring their age in years than months.

You can see a difference between a 12 month old and a 15 month old.
