Achondroplasia is a genetic disorder causing rhizomelic shortening of limbs. Head is often large with prominent forehead causing vaginal delivery difficult. A twenty-one years old multipara mother gave birth to a baby with achondroplasia via spontaneous vaginal delivery with episiotomy without any complication. Achondroplasia, in this case, was diagnosed on the basis of antenatal ultrasonography finding, clinical features and radiological finding of the baby. He was admitted in the special baby care unit for observation and discharged on the next day as no complications were noted.
