My baby's finger is peeling. Why is this happening?

A baby's circulatory system is still developing and blood is mainly channelled to vital organs and systems, where it's needed most. Therefore, baby's hands and feet are usually the last body parts to get a good blood supply. This could be a contributor to the peeling on his fingers. For newborns, it usually takes up to three months for his circulation to adapt completely to life post birth. As your baby grows older and becomes more mobile and active, his circulation will improve.
