Oh baby!

A onesie.

You've probably heard of it. That's the word used in babyland to describe an infant's piece of clothing.

Picture a miniature leotard. But, cuter. And snaps between the legs.

Keith Urban recently admitted he has never heard of a "onesie" until now. Better late than never. Keith and wife Nicole Kidman are expecting their first child this summer. That kid will own hundreds of onesies.

Back when I was expecting my first son, Griffin, I talked about my baby purchases with my co-hosts.

One day, on the air, Jim and Kevin asked me, "What is an Oh-nes-ie?"

After some snort-filled laughter, I realized what they were talking about.

That would be a ONESIE.

Let's hope Keith isn't getting his advice from my pals at work.
