Mother-To-Be retention belt Mother-To-Be® is a patented retention belt that prevents distrotion of the lumbar curve by transferring the weight of the extended abdomen from in front of the center of gravity, back to the spine and over the pelvis. The abdominal lift pad expands to accommodate growth. The Mother-To-Be retention belt can be ordered with or without an insert. The belt without an insert is designed for those whose pregnancy-related symptoms do not require the same degree of abdominal support. Clinically proven safe and effective.
