Rainbow baby is a baby that comes after a loss. Some people use the term and others don't-either is ok. DD3 is my rainbow baby and I even gave her the middle name Iris, which means rainbow.
What is a Rainbow Baby?
It is understood that the beauty of a rainbow does not negate the ravages of any storm. When a rainbow appears, it does not mean that the storm never happened or that we are not still dealing with its aftermath. It means that something beautiful and full of light has appeared in the midst of the darkness and clouds. Storm clouds may still hover, but the rainbow provides a counterbalance of color, energy and hope.
