Amy Duggar King and her husband, Dillion King, are fiercely protective of their 6-year-old son, Daxton. "We can't shield you from the whole world, but we will protect your world fiercely," Amy, 39, wrote via Instagram on Sunday, April 19, alongside a photo of her son. "Your safety, your steadiness and the life we're building around you." She continued, "Dad and I will never be passive about who we allow near you. Not everyone deserves a place in your story." Without detailing the inspiration of her post, Amy made it clear that her son's privacy was a top priority.
