If Christmas isn't a time for dressing up your baby in cute onesies, then we don't know what is. This "I drank Santa's milk" baby onesie sums up exactly what all kids are: innocent on the outside, but little hellraisers underneath. Still, at least this baby admits it. With a festive red and white design, this is the ultimate tongue-in-cheek baby Christmas wear. Dress your infants in this Christmas onesie to get a giggle out of Grandma, or take it up and notch and make them wear it for the family Christmas card. You'll have guaranteed laughs for years to come, especially when you bring the family album out on their graduation.
