A diaper insert has specifically configured contours on an inside surface to trap and contain bowel movements delivered within the diaper. An upper rear portion of the insert provides a protruding section of absorbent padding being contoured to match a lower lumbar region of the wearer. An upper front portion of the insert is provided with an additional absorbent pad to abut the abdominal area of the wearer. When a user, wearing a diaper equipped with the insert experiences a bowel movement, the padding sections contain the bowel movement within the diaper, and prevent the bowel movement from being secreted from a waist area of the diaper. In at least one (1) embodiment the insert is manufactured to be an integral portion of a diaper. In at least one (1) embodiment unitary rear and front barriers are removably added to a diaper.
