It's about the toddler in the earlier frame. The little girl with blonde hair. It's about a father's feelings about his daughter. "As she thoughtfully thumbs through her hair, And she purses her lips, bats her eyes and she plays, With me sitting there slack-jawed and nothing to say". That is exactly how my son-in-law looks at his new 4 month old. She makes faces, purses her lips, bats her eyes, plays, laughs and he melts. He says she is his Heart.
