That is one secret I would definately keep to yourselves! Maybe it would be a good idea to pick up a trimmer next trip to town.
A good one is the Wahl Peanut. You can find it at most Beauty Supply places like Sally's. Some people do just use the human trimmers like you can buy even at Walmart. But if you try the Peanut you will love it. And it might just save a minor war in case DH finds out his baby cheeks are sharing a razor with Freedom's baby cheeks of a different kind!
