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?

Because there’s a huge difference between a baby that just turned one and a baby that’s about to turn two. An expanded scale gives you a better description of where they are in growth progression.
