The Pitt-Jolie twins, Knox Leon and Vvienne Marcheline, received some special gifts from Daddy this week. Both children can now do their "tummy time" on play mats from Plain Mary which are monogrammed with their initials – – but in their case – – four letters because of their hyphenated last name. in addition, both children will use burpcloths emblazoned with "poop," "gross," "tinkle" and "poop" like below. They are really adorable!
