Definition - What does Rainbow Baby mean?
A rainbow baby is a child born to a parent or couple who have previously experienced miscarriage, stillbirth, neonatal loss, or the loss of an infant.
The birth of a rainbow baby can be a bittersweet experience for parents who are overjoyed by the birth of their child, while still mourning the loss of a child who has passed away.
FertilitySmarts explains Rainbow Baby
Rainbow baby is a term that is frequently used in trying to conceive (TTC) forums and infertility blogs. It is used to express the joy that has or will come with a successful pregnancy and delivery while remembering the previous loss.
It is also an easier way to communicate to others that a previous loss has been experienced, as the term is self-explanatory and does not requiring additional detail that may be personal or sensitive. Some may find it easier to say they are hoping for their rainbow baby rather than to state outright that they have experienced loss, particularly in an online setting.
Much like a rainbow appearing in nature after a dark storm, the birth of a rainbow baby brings light and joy after enduring the hardship of losing a child. This new joy does not negate the experience of previous loss, but rather the loss and new birth co-exist like a rainbow in a dark sky.
