Expectant Mother Joke

The expectant mother was looking for advice. She said, "Grandma,
when you and Grandpa had your first baby, did Grandpa ever handle
the middle-of-the-night feeding?" Her grandma replied, "No. I
always did that." The young woman laughed. "That must have been
before women's liberation." The grandmother responded, "No, it was
before we had baby bottles."
