Those lists of 400 things you MUST have always crack me up. As for nappies and convenience, I do an extra load every 3 days so I don't notice it. And I can't ever run out of nappies on a Sunday night, or run out of formula after dropping it all over the floor. And to the best of my knowledge, breasts have never been recalled but lots of formula is all over the world LOL. There's not a lot more convenient than "Lift top, whack baby on"
