No, Liam hasn't turned into Emeril.
After bathtime, in what I suppose is the logical progression -- at least to Liam -- of the game where Mommy & Daddy munch on baby belly, Liam made the statement "Liam's drinking Mama!"
Mama's response: "What, you're a vampire, now?"
This was met by what we initially thought to be very enthusiastic shouts of "vampire, I'm a vampire!" Then all of a sudden, he reared back and punched Daddy as hard has he could, yelling "Bam! Bam!!!"
Turns out, Liam actually thought that he had finally learned the word for a guy whose favorite activity is hitting things: "Bampire!"
Makes perfect sense to me! Now I just have to figure out how to pitch it to HBO...
