Many thanks for your question. I would be very causious about using the Aim Herbal Fibre Blend while breastfeeding, and especially with your baby being such a newborn.
This product is sold predominantly by Dischem pharmacies, and they advise that it only be used under the guidance of your medical practitioner while breastfeeding. This product is essentially used for eliminating parasites as well as body waste.
This product will pass through the breastmilk, and it is vital that your baby does not dehydrate due to the nature of this product. Rather ask your pharmacist or general practitioner for an alternative for yourself while still breastfeeding please.
Warmest regards and many thanks once again for your question.
