Kate Middletonis speaking out about the “isolation” she felt as a new mother.

The 38-year-old royal spoke with workers from a children and parents center in Cardiff, Wales, on Wednesday as she promoted hernew groundbreaking surveyon the early years of kids’ lives. She and husbandPrince Williamlived in Wales when they were first married, where he was stationed with the Royal Air Force.

The mom of three wasvisiting the innovative Ely and Careau Children’s Centrein an economically challenged area of the Welsh capital, where parents can get support as well as enroll their kids into the kindergarten.

“I see amazing work you’re doing here in so many areas,” she said. “It’s just bringing it to light. The critical work you’re doing has a massive social — and economic — impact later down the years.”

One of the center’s workers talked about how they tried to accommodate the concerns of parents who have questions raising their kids “this way or that way.” Kate said with a smile, “That’s why I wanted to do the survey. Unless parents are supported, it makes the job that much harder.”

Earlier, she met little River Rowson, 3, who was playing greengrocers with some pals. He was showing her some Brussels Sprouts and Broccoli. “Are you cooking too?” she asked as he offered some vegetables. “Are you going to make a stir fry?”

River clearly liked his new pal. “You’re my friend,” he told her, to which Kate replied, “You’re my friend too.”

Class teacher Rachel Fulthorpe tells PEOPLE, “She was really lovely, interested in the children. She got down to their level to speak to them in an age appropriate way. She was really friendly.”

In another class, she helped wipe a little girl’s hand. The center’s manager Carolyn Asante looked over and gave her the ultimate compliment: “You’ve got a job — when can you start?”
