Writing for Waitrose Weekend magazine, Kate Middleton‘s younger sister shared that she’s been bringing her baby boy to a cranial osteopath since he was 7 months old. “Soon after Arthur was born last year, I heard a few mums talking about seeing a cranial osteopath,” she said. “It’s a popular alternative therapy for newborns, particularly those who have had a traumatic birth, are unsettled, or have trouble sleeping,” she added. “It claims to heal, relax and promote sleep, digestion and body alignment through gentle head and body manipulation. While there is a lack of scientific evidence, after hearing positive things about it (and out of intrigue more than anything else), I took Arthur when he was seven months old.” Pippa, 36, revealed that she saw the effects immediately. “I was fascinated to see how calming it was for him, but also how valuable the feedback was,” she wrote. “The osteopath noticed one side of his neck was tighter than the other, which explained why he favored one side sleeping. She also saw that his arms were stronger than his legs, so she gave me an exercise to help him.” David M.

She added that although it’s an “expense,” it’s “well worth it.” After documenting how she stayed active during her pregnancy last year for the magazine, Pippa also shared that Arthur is following in her fitness footsteps by attending a baby gym. “Now that Arthur is 11 months old and more mobile, I have been trying to come up with different activities to do with him,” she wrote. “I needed to find something more than just park walks in the pram. Our local baby gym has been a saving grace. It’s a big space full of fun, soft objects, play mats, stairs, balls, swings, mini trampolines and more to stimulate and physically engage babies and toddlers.” Cranial osteopathy being performed on a baby. Pippa explained that in addition to free play, there are classes with “structured activities that help promote movement, balance and strength.” “Arthur burns lots of energy in this safe environment and learns many physical skills,” the mother of one said. “I have also noticed him building his confidence with each visit.” Pool/Samir Hussein/WireImage Can’t get enough of PEOPLE’s Royals coverage?
