That's according to an unearthed interview between Prince Harry and his long-time friend and conservationist Jane Goodall.
In the interview he revealed that there would only ever be two Sussex babies - max.
"I think, weirdly, because of the people that I’ve met and the places that I’ve been fortunate enough to go to, I’ve always had a connection and a love for nature. I view it differently now, without question," Harry said (per The Sun) during the Q&A, which appeared in the September 2019 issue of British Vogue, which was guest-edited by Meghan. "I’ve always wanted to try and ensure that, even before having a child and hoping to have children…"
At this point in the conversation, Goodall interrupted the royal to say that she hoped he and Meghan would have "not too many" kids.
Harry immediately alleviated any worries Goodall might have had, saying, "Two, maximum!"
It's not surprising that Harry, a longtime environmentalist, would want to stick to a two-kid limit.
“We are the one species on this planet that seems to think that this place belongs to us, and only us," Harry said, specifically in reference to mankind's impact on earth and environment. "But I’ve always thought: this place is borrowed. And, surely, being as intelligent as we all are, or as evolved as we all are supposed to be, we should be able to leave something better behind for the next generation." he said.
