Just as you fit one of a small number of stereotypes, so, too, does your partner. What, did you think we were only going to disparage you?
If your partner is a woman, then we commend you for your modern ways and invite you to switch some pronouns around; we think we've done enough already. If you're the one having the baby, she's probably wearing the pants in the family anyway, if you know what we mean. (We mean that she plays the guy.)
