Why did i have blue on the white part of my eyes when i was a baby?

Not sure: If your eyes are normal now your eyes were probably just not quite fully mature yet. The white part, sclera, is thick and irregular connective tissue that can appear slightly bluish in newborns but gets more dense as the eye grows. Genetic defects of collagen formation such as ehlers-danlos syndrome or osteogenesis imperfecta will have been discovered in you as a infant if this was the cause.

Thin sclera: Infant eyes have thin sclera (the white part) that allows the underlying black tissue to be seen. This gives the eye a blueish cast. As the sclera thickens, you can no longer see this.
