This year is huge for the two-year-old. Not only will she become a big sister, she’s expected to be one of the flower girls at Prince Harry and Meghan Markle‘s May 19 wedding.

And her mom, Kate, isn’t letting her pregnancy slow her down from her royal duties. The proud mom, who is a so close to her third trimester, dropped by King’s College London. This week, the royal was focusing her efforts on raising awareness on postpartum illnesses. Kate looked effortless in an all-blue Seraphine-designed outfit featuring here blue coat and trusty floral print dress, which she has brought out a few times during her third pregnancy.

She chatted with researchers at the Maurice Wohl Clinical Neuroscience Institute, who told her how avatars — computer representations of people — are used to help schizophrenic mothers. Kate surprised everyone, joking, “Oh, okay, as in the movie Avatar?”

Ian Everall, Dean of the Institute of Psychiatry, Psychology, and Neuroscience, explained, “No, it’s about people hearing voices. They create their own avatar, and they turn to their avatar and say, ‘Stop pestering me,’ and the voices go away.”

“Oh, interesting,” she responded. Kate then headed to the South of London, visiting the Mother and Baby Unit at the Bethlem Royal Hospital. They work on a treatment for postnatal depression and postpartum psychosis. The royal is hugely passionate about raising awareness about the struggles with motherhood.

Last year she shared her own accounts, confessing that at times she felt a “lack of confidence” and had “feelings of ignorance.” Catherine did explain while being a parent is “rewarding and wonderful,” it can also be very hard. “Personally, becoming a mother has been such a rewarding and wonderful experience,” she said. “However, at times it has also been a huge challenge. Even for me who has support at home that most mothers do not.”

“Nothing can really prepare you for you the sheer overwhelming experience of what it means to become a mother. It is full of complex emotions of joy, exhaustion, love, and worry, all mixed together,” she quipped. “Your fundamental identity changes overnight. You go from thinking of yourself as primarily an individual, to suddenly being a mother, first and foremost.”
