How sweet! Kate Middleton is ringing in her 37th birthday on Wednesday, Jan. 9, and her two younger kids, Prince George and Princess Charlotte, are so excited to celebrate their mom’s special day!

“George and Charlotte have already made their mom birthday cards in their arts and craft class,” a source exclusively told Closer Weekly. We’re sure Kate will be excited to open the thoughtful presents from her little ones when they get home from school, but until then, she’ll be enjoying her “adult time” with her mother, Carole Middleton!

“Whilst they’re at school during the day, Carole will celebrate with Kate by popping open a bottle of champagne and enjoying a nice lunch!” the insider continued.

Kensington Palace previously confirmed that Prince William would not be spending Kate’s birthday with her. The Duke of Cambridge instead made his first official 2019 visit to the London Air Ambulance to (ironically) celebrate 30 years of its existence. We’re sure Kate understood.

George and Charlotte are (obviously) big fans of gifts and celebrations, so it’s no surprise they made their mom the lovely cards. Kate and Will previously revealed that their little ones were up at 5 a.m. on Christmas morning to start opening gifts.

According to Hello!, a fan named Jill Lee revealed, “I said to Kate, ‘Were the children up early?’ and she said, ‘Very early, but it was lovely to see their faces.’”

And when George and Charlotte get old enough to go shopping on their own, we imagine they’ll head out for even more gifts for their mom. According to The Sun, Kate and her kids were actually spotted shopping at UK discount store The Ridge around Christmas time. Kate reportedly bought “trolley-loads of pictures, children’s books, and artist materials then queued at the tills.”

The family was even seen by onlookers, as one person said, “I recognized little Prince George holding Kate’s hand and ­Charlotte with a red bow in her hair. Their protection officers were keeping a discreet distance so they looked like any other family out grabbing last-minute Christmas bargains.” They’re so thoughtful already, just like their parents!
