Other than breast feeding, how else do mothers top fathers?

Carrying babies and delivering them. But then the men donate the sperm, so....

Exactly. It's like asking which hand is better, the left hand or the right hand.

Do mothers really top fathers? Doesn't everyone have their own role?

What kind of question is this? How can anyone compare mother's love with anything. Not saing that fathers do not love their children, but mother's love is different.
