There are a variety of reasons why supplementation to breast milk may be needed. Supplementation may look different, too. It could be pumping in between breast feeding opportunities at the breast for your little one, or using baby formula if breast milk supply is difficult to achieve. For some new moms, it is a temporary chapter to fill in a gap in caloric needs, while others may need to supplement their breast milk supply the duration of their time lactating. And that is ok! This is a delicate subject, I know. In terms of a full-term, otherwise healthy baby, this cycling as described below is mostly the reason why breastfeeding does not work out to the mother’s expectations.
