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?

Same reason I don’t talk about how many Billions of dollars I have.

The difference between 2 months and 10 months is a lot. If you don’t care about the difference, then you probably shouldn’t be having a conversation with a parent about their kids.
