Despite the fact that sunlight-dependent skin synthesis is the major mechanism for vitamin D synthesis in vivo, vitamin D-deficiency rickets continues to occur in exclusively breastfed infants in Greece. We present such a case in a 5-month-old infant who presented with afebrile seizures and whose mother was underexposed to sunlight due to veiling for religious reasons. Additionally, we briefly but thoroughly review the relevant medical literature. A high index of suspicion is required for nutritional rickets, when seizures occur in exclusively breastfed infants whose mothers have inadequate exposure to sunlight.
