She might be the cat your son dragged in, but you love her just as much as him. Your daughter-in-law has a warm soul, a caring nature, and a charming laugh that enabled her to sneak into your heart very quickly. For her birthday, let her know she's a perfect spouse. An important part of your family. And very, very deserving of an amazing day. Wish your daughter-in-law a spectacular birthday and treat yourself to her smile.
