Since Prince William and Kate Middleton welcomed Prince George into the world in July 2013 and proceeded to tote him along with them on various royal appointments, the world has had the privilege of witnessing nearly six years of what may be the cutest moments in the history of the royal family—and things have only gotten more adorable with Princess Charlotte and Prince Louis's arrivals. But it doesn't stop there: Now that Prince Harry and Meghan Markle have welcomed a baby of their own (hi, Archie Harrison Mountbatten-Windsor!), we're undoubtedly in for many more years of precious cousin hangouts and the antics of yet another pair of doting royal parents.
Some of the sweetest moments with the royal babies have come from William and Harry. There's something especially heartwarming about watching the brothers grow from young princes themselves to dreamboat college students to proud fathers unafraid to let their kids bring out their more sensitive sides. Here, alongside a selection of glorious photos much too pure for this world, are eight moments that prove Will and Harry already have this fatherhood thing on lock.
