Kate Middleton's Cutest Mommy Moments

Happy birthday to Kate Middleton! Today, the royally gorgeous Duchess of Cambridge turns 34. Considering she's one of the most beloved women in the world, both by the adoring public and her precious little family, we'd say Middleton has plenty to celebrate on her big day.

The last year was certainly a momentous one for the duchess: Most notably, Middleton gave birth to her second child, an adorable girl named Charlotte Elizabeth Diana. Luckily, Mom likely won't have too much to worry about as little Princess Charlotte grows up in the public eye. After all, she'll have her stylish and quite studly older brother, 2-year-old Prince George, to look up to in the coming years. Not only that, but we have a feeling Kate's hubby, Prince William, is quite the dad. One sweet example? In a recent interview, he shared that being a father to Charlotte and George has made him "a lot more emotional."

Can you say cutest royal family ever? See 11 of Duchess Kate's most heart-warming photos with her children starting with the royal Christmas card photo above.
