I didn’t think Karston would learn that Mr. Wood was trouble until he was teenager or older. He woke up crying twice last night (yawn), so we changed his diaper to avoid a diaper leak since that’s what crying usually means now. Both times I noticed that Mr. Wood had visited him recently, so he was pointing up (high chance of a leak) instead of down (only overflow leaks). So I think Karston knows Mr. Wood causes diaper leaks, and he knows he’s too old for malfunctions like that, so he let us know.
