I have to respectfully disagree with this clause from the Vice Guide to Everything:

Men are not allowed to wear any kind of baby-carrying knapsack. A kid only weighs 30 pounds, and if you can't carry that, you're not much of a dad.

30 pounds is the weight of two bowling balls. Except unlike bowling balls, kids don't come with finger holds, and are rangy and move while you carry them. My kid is only at the one-bowling-ball weight, and I've been holding him a lot today and it hurts (though maybe I also have the swine flu). It's true if you can't pick up your kid, you're not much of a dad, but carrying the fuckers around hurts. Gavin McInnes does not have kids and doesn't know what he's talking about.
