Mike Tindall opens up about George and Charlotte

Mike and Zara Tindall are close to the Duke and Duchess of Cambridge and both Prince George and Princess Charlotte have grown up alongside their eldest daughter, Mia.

Photos of the parents playing with each other's children demonstrate their closeness.

Mike previously told HELLO! about their special relationship.

"They’re all quite close in age and hopefully they’ll grow up as good friends," he said.

He has told The Telegraph that the arrival of Archie, the first child of the Duke and Duchess of Sussex, has led him to reflect on Harry as a dad.

Prince Harry is the godfather of Mike and Zara's second child, daughter Lena.

"Obviously, he's godfather to Lena, but we've got a great group of young ones in the family now," he said. "Lena, and obviously Louis, are similar ages and Mia's sort of in between Charlotte and George, and then you’ve got Peter's children, Savannah and Isla, who are just a little bit older."

Peter Phillips is Princess Anne's son. He is married to Canadian management consultant Autumn Kelly.

Tindall said he hoped Harry and Meghan have the same luck when it comes to Archie's sleeping schedule as they did with their daughters.

"The thing is, we're so lucky with ours; ours have always slept so hopefully they'll get that as well," he said.
