It’s been a busy week for everybody’s favorite royal mom-to-be! Kate Middleton has stepped out for the second time this week to officially open the new London headquarters for Place2Be, a children’s mental health charity. Kate — who is just weeks away from welcoming her third child into the world — was all smiles as she took part in a discussion with mental health professionals and school leaders. She also met with staff and pupils from Albion Primary School in Rotherhithe, London, where Place2Be has been providing mental health support for pupils, families, and staff for over a decade.

While at the school, Kate, who is a patron of the charity, looked on as children drew inside the outline of a paper hand, before suggesting she take one of the coloring sheets “home to do with Prince George and Princess Charlotte.” During the outing, Kate, 36, recycled a blue lace Marlene maternity cocktail dress from Séraphine. The sold-out frock, which features bell cuffs and an empire-waist, has become a staple of the pregnant royal’s closet. She previously wore the dress for a luncheon with Norway’s King Harald and Queen Sonja during her recent royal tour with husband Prince William.

The royal mom has certainly stuck to a blue-theme this pregnancy — from that first lacy blue Temperley dress in October to her gown at the Royal Variety Performance in December. And while royal bookies are betting that the blue is a nod to the gender of the baby, as the Daily Mail reported, we’re going to need a little more evidence. Kate and William have stayed pretty tight-lipped on the details surrounding their third child, other than confirming the new arrival is due sometime in April. But according to a fresh report by UK paper The Sun, Kate’s due date could fall on a very patriotic holiday.

The publication has claimed that the royal couple will welcome their bundle of joy “on or around” St. George’s Day on Monday, April 23. St. George’s Day is celebrated by Christian denominations around the world and honors the Feast of Saint George. “There’s no certainty with due dates, of course, but the Duchess is working off a date around St. George’s Day and it would be a lovely patriotic coincidence if he or she were born then,” an insider explained. “Or if she’s very late, as she was with George’s birth, she could even make it a very special wedding anniversary present to William, as they celebrate seven years of marriage on [April 29].”

Similar to her pregnancies with both George and Charlotte, Kate and William have reportedly decided not to find out the gender of their baby, The Sun also reported. It’s also claimed that she’ll give again birth at the Lindo Wing of St. Mary’s Hospital in London, just like she did with her two other babies. We can barely wait!
