Here's what happens if your 3 year old says "high" instead of "tall" :

Cason: Mom, I'm so high.

Me: How high are you?

Cason: I'm this high (showing with his arms). When I was two I was this high. When I'm five I'll be higher. Mom, how high are you?

Me: I'm this high.

Cason: How high is Daddy?

Me: Daddy's about this high.

Cason: Who's higher, you or Daddy?

Me: Daddy is definitely more high than me.

Cason: My friend Haley is high too. And Alli is higher than me (sorry you were dragged into this Haley and Alli). But I'm really high. REALLY, REALLY high.

And now I have the song, "Because I got High" in my head.
