I do not have a baby, but I have a sous vide circulator (the light of my life), and I assume that other people who own sous vide circulators might one day procreate. (Or maybe they already have!) For these offspring-having, sous-vide-savvy home cooks, I have great news: You can use your sous vide setup to warm breast milk and baby formula to the perfect 37C, without fear of overheating it.
