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?

I saw a video on tiktok that exemplified this. A 1 year old and 1 month is a baby, he can sit, but not walk, maybe talk. A 1 year old and 11 months can walk, talk, and is a toddler almost. It’s a really big difference between them.
