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

Many important developmental milestones happen during the first two years of life. And it can be difficult to gauge an infant’s age based solely on its size. The changes happen rapidly. There are huge differences between a 12 month old, and an 18 month old. And between 18 mos and 24 mos. Measuring age in months when changes happen so frequently is a more accurate shorthand to convey what stage of development the baby is in.
