Objective: to explore written statements found in online discussion boards where parents currently expecting, or with previous experience of expecting, a child with a prenatally diagnosed congenital anomaly communicate about their emotional process from diagnosis to birth. Design: cross-sectional qualitative study of messages in public online discussion boards. Setting: Swedish public discussion boards about reproductive subjects. Sample: ten pregnant women and eight parents (of children with prenatal diagnoses) who had written 852 messages in five threads in Swedish online discussion boards identified via systematic searches. Measurements and findings: three phases were identified in the process of moving from the diagnosis to the birth: shock, existential crisis, and life remodeling. The people posting message (‘posters’) moved from initial shock to existential crisis and, lastly, a phase of remodeling life later in the pregnancy. During the pregnancy, considerable worries about both antenatal and postnatal aspects were expressed. To cope with their situation, the posters distanced themselves from the diagnoses, vented their feelings, sought control, and obtained practical support from friends and relatives. Key conclusions: expectant parents faced with a prenatal diagnosis move from initial shock to a phase of life remodeling and acceptance. Burdened with considerable worries, expectant parents cope with their situation through informational, emotional, and instrumental support from health professionals, family, friends, and peers. Implications for practice: health professionals should make sure that expectant parents feel involved in planning their children’s postnatal care, that they are offered sufficient information, and that they have access to emotional and instrumental support structures.
