I asked Benjamin this afternoon if he had the hiccups and he said "yeah, pickups."
Then, a few minutes later, he saw our bottle of hydrogen peroxide which I used to clean a cut he had the other day and he pointed to it and said "owie, owie." I said "yep, I used that to clean your cut the other day so it wouldn't get infected." He said "infested." Incidentally, the cut got neither infected nor infested. :)
