Princess Eugenie has shared an adorable first video of her baby son August to mark a day close to her heart.
In clips uploaded to the royal mum's Instagram Stories on Tuesday, the four-month-old can be heard gurgling happily to himself in his baby bouncer as he plays with a blue fluffy toy shark - which appears to be from WWF UK.
Eugenie captioned the videos, writing: "It's World Oceans Day today. A day to celebrate our magnificent oceans and all the creatures in it."
