The little Mia wants to play Rugby, very rough sport. Well more power to her. She is Daddy's little girl.
Zara is no shrinking violet either; i'm sure it takes guts to do those horsey thing (you can see i know nothing about horses, in fact i think it takes a lot of guts to even get on a whopping big horse)
Mia is so obviously a chip off the old block from both her parents. She looks like a lovely delightful energetic wee girl.
