The part we don’t always see…
In lactation care, we are trained to look closely, at latch, transfer, positioning, and supply. And yet, sometimes the most important barrier to breastfeeding success isn’t at the breast at all. It’s biochemical.
Vitamin B₁₂ deficiency is one of those quiet disruptors. It doesn’t always announce itself clearly. It doesn’t always show up on the first visit. But when it’s present, it can shape the entire feeding experience, for both mother and baby.
And if we miss it, we risk mislabeling the problem. A dyad issue, not an individual one. Vitamin B₁₂ deficiency in infancy is rarely an isolated infant condition. It is, almost always, a maternal–infant dyad issue.
