Rosie is the pony shared by two girls, Cally and Mia, whom Tilly meets on her first visit to Silver Shoe Farm. Rosie is a lovely pony, with a sweet and gentle temperament…

Tilly mounted and adjusted her position until she found her balance. She sat into the lowest part of the saddle with her hips square. It felt great – Rosie was the perfect size for her.
        “Be clear with your leg aid as you ask her to move forward,”Angela instructed. “Use your legs and allow her to move forward by softening your arm. I don’t want to see too much bouncing today – remember what we said about rising in rhythm to the trot.”
        Tilly started with a walk, so that she could get used to Rosie’s movement.
        “That’s it. Don’t tighten up. Imagine you’re a wet noodle – completely relaxed."
