Breastfeeding Support Group
While breastfeeding is recommended by many doctors, it is not as simple as it seems. This is a community dedicated to parents who are choosing to breastfeed, providing a safe place to discuss everything from pumping, to questions of whether baby is getting enough, weaning, breast care, scheduling, supply, and more.
