There’s that joke about using months for your kids age way past a normal range, but the other day I figured out the benefits of the month based age system. I was asked how old my child was and was questioning my sanity. " 2? 3? Uhh… 2.5…" I mean 6 months is 25% of a two year olds life. To add to that, the 9 months of pregnancy, the late nights of screaming and crying that make you forget what year it is.

At least when you count the months you are within a close range when you get it wrong. Saying your kid is 2 or 3 years old is like saying your grandpa is either 66 or 99.
