They're getting younger and younger

I heard an advertisement on the radio for a dance studio, and they accept children aged 18 months and up. Can infants who are a year and a half old really be coordinated enough to dance, let alone follow instructions and comprehend what to do? Now, granted, I don't know much about little kids (don't make me deal with them until they're at least 2.5), but you had asked me, I wouldn't have even been sure that 18 month olds could walk, let alone dance.

It does remind me of a scene in the Gilmore Girls' pilot. I'd describe it to you, but I really can't do it justice, so you'll have to watch it for yourself.
