But she told the U.K.’s Sunday Times in an interview alongside her brother, Peter Phillips, that she “then had another miscarriage really early on.”
Zara, 37, adds, “You need to go through a period where you don’t talk about it because it’s too raw but, as with everything, time’s a great healer.
Last week, Zara’s husband, Mike Tindall, told PEOPLE that the couple are loving life as a family of four. “It’s been brilliant so far. I can’t complain,” the 39-year-old former rugby star said. “[Lena] eats, sleeps.”
Zara, a former Olympian and equestrian, adds that she “shocked myself” when Mia arrived as she had not been “very maternal.”
“If someone had a new baby and said, ‘Do you want to hold my baby?’ I’d go, ‘No thanks,’ but I really enjoyed all of it when I had Mia,” she said.
“Mia is about to start school; with Lena, who is a month old, I’m going back and doing it all again.”
