11 Photos Of Prince William & Prince Harry As Kids, 'Cause The New Royal Sibling Pair Will Follow In Their Footsteps

The moment we've all been waiting for is finally here. Kate Middleton has given birth to her second baby. According to the official Kensington Palace Twitter account, Middleton welcomed a baby girl at 8:34 a.m. BST who weighs 8 lbs., 3 oz. Mother and child are both said to be doing well. Of course, this is very exciting news, but now that Prince George is a big brother, I'm looking forward to seeing photos of both of Middleton and Prince William's children together. And as siblings, I'm hoping they're as precious as Prince William and Prince Harry were together when they were kids.

Since both Prince William and Prince Harry are both all grown up now, you might've forgotten — or maybe you weren't alive, which is even scarier — how adorable they were as children. Whether they were chilling around the palace or making formal appearances, it's always been clear how much they love each other and how much kids will still be goofy even if they're part of the royal family. I predict that there will be a similar relationship between Prince George and his new baby sister, and if they end up emulating their dad and his brother, they'll be a pretty lucky pair.

They'll play piano together

They'll sport matching outfits

They'll joke around during serious official engagements

And they will do basically everything together

They'll play with their pets together, especially with their dog, Lupo

They'll clown around for ridiculously cute photos with their mom

And participate in many awkward family photos

They'll probably be pretty bored with the not-so-fun parts of being royal

They will make the Royal Grandma nuts

They'll go to school together in matching dorky uniforms

And eventually, they will grow up to mock others on Twitter, just like the rest of us
