Can you believe it’s been a year since Prince Louis was born? The youngest child of Prince William and Duchess Catherine turns one on April 23, and he just had a photo shoot to celebrate the occasion.

Kensington Palace just shared some photos on April 22, which were taken by Kate Middleton at the family’s home. The little tot is all smiles as he crawls through the garden with his sweater covered in grass, and you’ll notice two tiny teeth in his bottom gum.

Compared to his siblings’ first birthday photos, those we’ve seen so far of Prince Louis feature a less formal setting and playful jaunt in grass clippings. For Prince George, a photo session was arranged for the family at the Natural History Museum in London and they were shot by a professional photographer.

Princess Charlotte was the apple of her mother’s eye as the duchess snapped shots of her playing at home, just before her first birthday. What do they all have in common? Rosy cheeks and side-swept hair!

Check out the adorable pics – and that cute dog sweater – by clicking below and compare for yourself how much the royal trio have in common when it comes to being photogenic. Now, we just want to know if there will be cake-face photos coming too. Our guess is only as good as yours!
