But you could just put a baby wipe or a washcloth, or the diaper itself, over the baby, and it would work just as well.

"I think there are a lot of these little products that come along and (parents) think this would help save Western civilization if we just had this little product to keep my baby from peeing on them," said Alan Fields, who co-authored the book "Baby Bargains" with his wife.

Besides, once you pull the wipe out and air hits it, it starts cooling off. Truthfully, all you need is some wipes. And cold ones will do.

"Sure, the wipes may be a little cool on baby's bottom, but the crying the baby is doing probably has something more to do with the fact he's wet and doesn't like the draft caused when his diaper is removed while on the changing table," Pericon said.

But when your baby is screaming, three minutes is an awfully long time to get baby drinking a bottle cold or at room temperature. Even better, get your child used to drinking a cold bottle anyway, because when you're out and about, there usually isn't a warmer (although you can actually buy a car bottle warmer, too).

But you probably already have some good alternatives in your kitchen. You could sterilize everything in the dishwasher, or go real retro: Drop those nipples and pacifiers into a pot of boiling water on the stove.
