The mother of two suffers from hyperemesis gravidarum, a severe form of morning sickness in her pregnancies, and it forced her to miss several engagements, including Prince George’s first day of school.
“The duchess’ condition is improving but she’s still suffering from hyperemesis gravidarum,” a royal aide told E! News. “She’s delighted to be here tonight.”
“It was Catherine who first realized that all three of us were working on mental health in our individual areas of focus,” he said. “She had seen that at the core of adult issues like addiction and family breakdown, unresolved childhood mental health issues were often part of the problem.”
