Duchess of Cambridge, Catherine, revealed the ‘important’ thing she tells her children Prince George and Princess Charlotte while at an event on Tuesday.

The mum-of-three was out for a royal engagement with husband William, at Basildon Sporting Centre, where she met people working with Coach Core.

The apprenticeship programme, which is part of the Royal Foundation, helps young people who are not in education, employment or training to build a career in sports coaching.

The couple even got involved in the activities, with Catherine playing one of her favourite sports – tennis.

During the engagement, the Duchess was sweetly hugged by a royal fan, Janet Emery, and as Catherine hugged her back, she opened up about how important hugs are and how it’s something she tells her little ones.

She said, “Hugs are very important. That’s what I tell my children.”

The sweet moment saw Catherine following in the footsteps of her sister-in-law, Meghan, who often hugs well-wishers at royal engagements.

While hugs are not exactly out of the question, royal protocol dictates that when meeting the Queen or any member of the royal family, men should bow from the neck only and women should curtsy, or go for simple hand shake if they offer it first.
