If the doctor has diagnosed your baby, he will receive vitamin K shot (1 mg or depending on your baby’s needs) immediately. This will increase the blood’s clotting ability within 2-3 hours. Your baby may receive oral supplements of vitamin K instead of shots [7]. This is determined by your baby’s doctor. The oral dose will depend on your baby’s needs as her doctor sees fit. For babies with severe bleeding, a blood transfusion may be necessary [8].
