Rizzo is diagnosed with Rett syndrome, which leads to a regression of basic skills that a small child may have already learned.
Her parents say that the volunteers at Sebastian Riding Associates have made a huge difference in their lives.
They continue to document Rizzo's life on Instagram, @little.big.learner, in hopes to raise awareness for Rett syndrome.
