Baby Archie turned one on Wednesday. On the occasion of his birthday, parents Prince Harry and Meghan Markle released an adorable video of the duchess reading to her young son.

The three-minute long clip shows the royal mother read one of Archie's favourite books "Duck! Rabbit!" as filmed by the Duke of Sussex. The video was filmed as a contribution to an ongoing campaign Save the Children's #SaveWithStories whereby celebrities are recording and posting videos of them narrating classic stories in an endeavour to raise funds to save children being affected by the coronavirus pandemic.

In the video posted on the campaigns official Instagram page Meghan Markle is seen reading the book to her son on his birthday. Archie can be seen turning the pages as he sits on his mother's lap enjoying the book. And towards the end, Prince Harry, who is filming the video can be heard laughing and cheering little Archie.
