Okay kiddo, let's talk about half a dozen babies. Have you ever heard of a dozen? It means 12 of something, like 12 cookies or 12 crayons. So if we're talking about half a dozen, that means we're talking about half of 12.
So let's start with 12 babies. That's a lot of babies, right? Now if we take away 6 of those babies, we're left with half a dozen babies. Half of 12 is 6.
Basically, half a dozen babies just means 6 babies. It's just a different way of saying it. So if someone says there are half a dozen babies in a room, you know there are 6 babies in there.
