Vitamin D: If you are breast feeding, it is good to continue your pre-natal vitamins and to give your baby supplements of Vitamin A,,C and D that are not supplied by your breast milk. I do not know what is available in Germany, but in the US there is a product called Tri-Vi-Sol that are drops that are available without an Rx and recommended for breast fed babies. See if there is something similar there.

Why ?: There are liquid (dropper) vitamin preparations of vitamins ADE and K or vitamin D alone available for use when needed.
