A baby stands up in her crib. She crawls on the carpet and a woman picks her up. On a changing table the baby lies naked as a hand rubs Vaseline on her bottom. Baby lotion is put on one strainer and petroleum jelly is put on another. Water passes through the strainer covered with lotion but not the one covered in Vaseline. The baby lies down on the changing table in her diaper and plays with the jar of Vaseline. A shot of a jar and a tube of Vaseline.
