I'm fairly certain Lydia can't tell the difference between the words "taste" and "chase."
One of our favorite games recently is "Chase," where she pretends to be a puppy and crawls around chasing me. I run off yelling that she's going to get me and I'm so scared and oh what am I going to do and save me Baby Rafe and I can't get away, etc. Laughing hysterically, she crawls up to me and...wait for it...licks my leg. She's "tasting" me. She thinks we're playing a rollicking game of "Taste."
It inevitably ends with an icky face and the astonishing proclamation. "Mama taste yucky. Want to play taste wi Dada."
