We're halfway through the year, and we've already been treated to a handful of sweet moments from our favorite little royals: Prince George and Princess Charlotte. And what's even more exciting is that now newborn Prince Louis is in the mix! While we haven't seen much of baby Louis other than his hospital arrival and first official portraits, we're sure to get a glimpse of the newest Cambridge at his christening.

Scroll through to see the cutest pictures of the royal kids this year, so far!
