Nick and Vanessa Lachey's son, Camden, is getting so big! The couple took their adorable 3-year-old to Disneyland in Anaheim, CA, on Tuesday, and the little one is already quite a natural with the camera. In the cute family snapshot [1], Camden is seen wearing a large pair of Babiator sunglasses as he flashes a smile while holding on to his mom. Nick and Vanessa are also sporting cute his-and-her mouse ears. The couple, who welcomed Camden in September 2012, left their 8-month-old daughter, Brooklyn [2], at home for the outing. See the sweet snap above, and then check out what Nick had to tell us about his sweet family life [3].
