It's hard to keep a secret when you're a member of the royal family, but somehow Kate Middleton managed to do just that.
Despite being in her third trimester, the Duchess of Cambridge has been making several public appearances with a genuine smile plastered on her face.
This Tuesday, Middleton and her husband, Prince William, visited an outdoor ice-skating rink in the center of Stockholm, Sweden to play a game of bandy hockey and meet the local schoolchildren.
But that wasn't the first time she's met kids this year. On January 22, Middleton went to an elementary school in London to talk about the importance of taking care of your mental health.
"I see time and time again that there is so much to be gained from talking of mental health and taking the mental health of our children as seriously as we do their physical health," Middleton said. "When we intervene early in life, we help avoid problems that are much more challenging to address in adulthood."
While the royal makes time in her busy schedule to bring awareness to causes close to her heart, she doesn't always put her good deeds on display.
