Mentioned in: "The Fight" (season 3, episode 13)
The issue that plague this idea actually becomes the jumping-off point that Tom's one potentially good idea, Rent-a-Swag. Babies grow quickly, so buying them expensive clothes (tuxedos, for instance) isn't the best idea for someone without disposable income. A baby's first tuxedo will inevitably end up in the donation pile a few months later.
On the other hand, for those who do have a ton of burnable cash, don't be the asshole who dresses their baby in a tuxedo. It's not cute. Your baby doesn't have swag. Unless your baby is Blue Ivy, of course.
