On January 7, Sheikh Mo's son, Sheikh Zayed, turned six.
Though he's the youngest of Sheikh Mo's children, little Zayed certainly follows in his father's footsteps. Photos shared by his family throughout the year show the young royal playing in the desert, visiting some of the country's most historic landmarks, and taking part in the family pastime, horseback riding.
In honor of her son's birthday, Princess Haya shared a photo of the boy with his doting father.
"Happy Birthday to our little Zayed .... you bring us so much joy! We love you," she captioned the photo, adding the hashtags, "#BirthdayBoy #SixYearsOld #MyDubai."
