Vitamin K is an essential vitamin required for the activation of coagulation factors II, VII, IX, X, and proteins C and S. The deficiency of vitamin K leads to coagulopathy leading to the development of vitamin K deficiency bleeding (VKDB). We present a case of a 2-month-old male child who presented with tonic posturing of all 4 limbs. At birth, vitamin k was not administered. The neonatal period was uneventful, and the child was exclusively breastfed. On further evaluation, a subdural hematoma was detected. A diagnosis of late-onset vitamin k deficiency was suspected. Treatment with intravenous vitamin K was started with complete recovery. The diagnosis of late-onset VKDB should be suspected when an intracranial hemorrhage in a previously healthy newborn is found especially when there is no history of Vitamin K administration after birth
