Meghan Markle and Prince Harry marked her first Mother's Day as a mom with a sweet photo of royal baby Archie Harrison Mountbatten-Windsor — and a tribute to Prince Harry's late mother, Princess Diana.

The new parents posted a photo on their @SussexRoyal Instagram account of Duchess Meghan's hands holding baby Archie's feet.

Princess Diana's favorite flowers, forget-me-nots, can be seen in the background.

Today is Mother’s Day in the United States, Canada, Australia, New Zealand, South Africa, Kenya, Japan, and several countries across Europe. This is the first Mother’s Day for The Duchess of Sussex."
