What sort of disease is a baby being too large for his mother's pelvis?

Not always disease: Fetal growth can be greater than normal if maternal diabetes or certain genetic conditions. Babies can be too large than their mothers' pelvic outlet if that outlet is narrow or if the baby is large, eg, overdue. It is important to know the mother's medical and obstetric history and risk factors and an ultrasound estimate of fetal weight before delivery if there is a concern.

Baby will not fit: "baby being too large for mothers pelvis" means that due to the shape and size of the passage between the pelvic bones the baby will not be able to fit during birth. This means that there will be failure in descensus of the baby's presenting part . This is typically diagnosed during labor with vaginal exams when your doctor checks for how low the baby's head is getting in relation to the pelvis.
Dr. David Bergman

CPD: This isn't a disease. There are many different shapes that a women's pelvic bones can have. Babies won't always fit thru the bony structure of a women's pelvis. Therefore the size of the baby relative to the size of a women's pelvis determines her ability to deliver the baby vaginally. This is called cephalo (head) pelvic (bone) disproportion. Or cpd.

Are the symptoms of a baby too large for mother's pelvis?

Labor disorder: Most women who are having their first baby are candidates for a trial of labor/to try to have their baby vaginally. The progress of labor is closely monitored, as well as the prenatal history, to give guidance to baby's size. Abnormal diabetes screening in pregnancy may be a clue. At the time of labor if descent, dilation or progress are abnormal a cesarean may be indicated.
