Yes, it is recommended that you take Pregnancy Vitamins while breastfeeding for at least 6 to 12 months after giving birth. Breastfeeding is a nutritionally demanding period in a Woman’s life and thus supplementing Vitamins and Minerals that are lost through the Breastfeeding process is important. Preggy-Mama can be used before, during and after Pregnancy and throughout the Breastfeeding process.
