The experiences and needs of mothers who lose a newborn twin were explored by sending semistructured questionnaires to 14 bereaved mothers. All mothers continued to think of the surviving child as a twin. Six had feelings of resentment towards the survivor. All felt their loss had been underestimated. Support could be improved by acknowledging the mother's grief and encouraging her to talk about the dead baby. Zygosity should be determined and reminders, such as photographs (of the babies together) and ultrasound scans, provided. All parents should be offered counselling and the opportunity to meet similarly bereaved parents.
