Vitamin D Drops while breastfeeding?

Parker • 18 💞 Astrid’s mama 💕

Our pediatrician told us to get Vitamin D Drops and give them to our daughter she’s 4 days old. She said it’s because I’m breastfeeding and not bottle feeding. I’ve never heard of this before is it normal? I thought breastfeeding they get all the nutrients they need without any supplement.
