A woman is sitting in a pediatrician's examining room with a baby on her lap. The doctor arrived, examined the baby, and after checking his weight, asked if the baby was breast-fed or bottle-fed.
"Breast-fed," she replies.
"Well, strip down to your waist," the doctor ordered.
She did. He pinched her nipples, pressed, kneaded & rubbed both breasts for a while in a very professional and detailed examination. Motioning to her to get dressed, the doctor said, "No wonder this baby is underweight. You don't have any milk."
"I know," she said, "I'm his Grandma, but I'm glad I came in today."
