Today, April 23rd, the British royal family grew by one when Kate Middleton gave birth to her third child. So far, little is known about the royal baby, but we’re still bursting with excitement at the news that Princess Charlotte and Prince George have a new brother. We can’t wait to see these three royal siblings grow up together but, in the meantime, let’s reminisce on some of the cutest moments featuring George and Charlotte.

Born in July 2013, George is the eldest of William and Kate’s children. He became a big brother when Charlotte was born in May 2015. The two royal siblings continue to grow, looking more like their parents every day. And even at the ages of 4 and 2, the prince and princess are making history. Charlotte is the first ever princess to keep her spot in the royal succession after the birth of a younger brother. And when William and Kate sent George off to school in September, they enrolled him in a different primary school than the one his father attended, making for an original choice.

We’re sure that George, Charlotte, and their new brother will make great, influential leaders some day, but right now we’re looking forward to watching them grow and play together.
