I am hoping maybe someone here can help me. I have a friend that has 3 small children. Her oldest child is 2 1/2 & although the oldest, still wears size 6-9 months & is very tiny. They would love to go to Disney next year but they are worried that she will not be able to ride any rides. I remember taking my 18 month old on tons of things when we first went. What is the policy for a tiny child? Does anyone know?
