Episode Overview
Katie is certain she can distinguish the triplets by name, but the rest of the family remains skeptical. When Steve steps in to give them a bath, Katie confesses that she can’t tell them apart anymore since he washed away the ink dots on their feet that helped identify them. To resolve the confusion, they need to return to the hospital for a proper identification process.
