Kate Middleton is opening up about the challenges of motherhood.

The Duchess of Cambridge — who is mom to 5-year-old son Prince George, 3-year-old daughter Princess Charlotte, and 9-month-old son Prince Louis — got candid with parents during a visit to the Family Action charity on Tuesday.

“It’s so hard. You get a lot of support with the baby as a mother particularly in the early days, but after the age of 1 it falls away,” Middleton, 37, said via People. “After that there isn’t a huge amount — lots of books to read.”

She continued: “Everybody experiences the same struggle."

According to People, Middleton helped launch a new U.K. support line for Family Action, which uses a network of volunteers to give virtual support to parents and caregivers.
