Meghan's mum Doria Ragland arrived last week ahead of the birth of her first grandchild, with the pair practising yoga together.
Meghan and Harry have officially moved out of their Kensington Palace home and into their new Frogmore cottage in the grounds of Windsor Castle, which they reportedly spent £3 million renovating.
