I believe that every child needs to try different experiences as they are growing and maturing... there is nothing wrong with a boy playing with dolls or a girl climbing trees and playing with trucks... it DOESN'T mean that the child is not the gender of their anatomical parts. A child tries different roles to see how s/he fits in the world. To have an adult lock them into transgender at such an early age is appalling. When that child is fully mature and can make that decision is soon enough.
