This is probably the #1 reason to have a kid:
$34.95 Baby Mop Onesie
It's like a swiffer that someday will need college tuition.
For real though, babies are on the floor anyway, and you have to change their outfits all the time from what I understand because they are always puking or pooping, so you might as well get your floors dusted.
They come in Boy, Girl, or Neutral which I sadly assume means blue, pink, or yellow, but I am not sure.
