Pippa Middleton Opens Up About Baby Arthur, 6 Months, for the First Time (He's Learning to Swim!)

The younger sister of Kate Middleton welcomed her first child with husband James Matthews in October

Pippa Middleton is passing her passion for sports onto her son!

The younger sister of Kate Middleton opened up about being a mother to 6-month-old Arthur for the first time in U.K. supermarket monthly Waitrose Kitchen magazine. After previously sharing how swimming helped her stay fit during pregnancy, Pippa revealed that Arthur is already loving the water.

“Starting my son Arthur swimming at four months old has given him confidence and enjoyment in water,” she wrote, according to the Instagram fan page MiddletonMaven. “He’s now six months old, and swimming is one of our favorite activities. The exercise helps guarantee sound daytime sleeps, and the movement has improved his digestion.”

Pippa, 35, previously said swimming had become a go-to way to keep up her fitness routine as she neared her due date.

“From personal experience, I’d confidently say I find it has been the most enjoyable and rewarding form of exercise since I found out I was expecting,” she shared. “It’s comforting to know that it’s safe throughout pregnancy, and you don’t need to adapt and change too much (unlike most other sports). It’s so good for you that you could swim every day – as long as you don’t overexert yourself – right up until the end of the third trimester.”

Pippa and husband James Matthews have been spotted around London and on vacation in St. Barts since becoming parents, but she made her first official post-baby outing at a charity gala event in late February.

A source previously told PEOPLE that Pippa and James are looking forward to settling down and “having children and leading a quiet life.”
