Open Letter to Parents
When I ask how old your child is, I don't want to perform any kind of arithmetic, however simple. If your baby is at least one month old, state your baby's age in months, not weeks. If your toddler has hit the year mark, start using years for his age, not months.
Here's an example:
Me: "Oh! How old is he?"
You: "18 months."
Me: Okaaay . . . 12 months is a year, and 18 months is 6 more months than 12, so he's a year and a half. Wait. Why didn't she just say a year and a half?
See how much work I have to do? It's annoying.
