Meghan Markle will celebrate her first Mother's Day as a new mum on Sunday, just days after the birth of Archie Harrison, who was born on Monday, May 6.
WATCH Harry and Meghan introduce baby Archie to the world for the first time.
Although in the UK, Mothering Sunday was on March 31 this year, as she grew up in the US, the Duchess will also celebrate the special day this Sunday.
The US observes Mother's Day on the same day we celebrate and give thanks to all mothers here in Australia.
A source tells ET that 37-year-old Meghan plans to spend her first American Mother's Day at home in Windsor with her family.
Her own mother, Doria Ragland, will also be there to enjoy the Sussex's celebrations.
