That's cute! When my daughter was just learning to talk, those little black lumpy things that you burn in the barbeque were "chuckle". Took me quite a while to figure that one out. We went all through the grocery store with her in the baby seat of the cart, telling me not to forget the "chuckle" before I realized that she meant "charcoal". To her, a helicopter was a "hot-hopter" and a bicycle was a "bice-pipple".
I know I shouldn't let it bother me but it's really annoys me to see adults who don't seem to know the difference between "to", "two" and "too". Also "then" and "than". I'm occasionally guilty of this one myself, but if I do it, it's a typo - I do know the difference.
