When babies are formula fed from birth, they miss colostrum… the first milk made specifically for the first days of life.
Colostrum is highly concentrated and time sensitive, designed to protect newborns while their immune system and gut are still immature. Without colostrum, babies miss early immune protection from human antibodies like secretory IgA, which coat the gut and help block bacteria and viruses. They also miss living immune cells that actively fight infection and help guide immune development… something formula cannot provide.
Colostrum helps mature and protect the newborn gut through growth factors that reduce intestinal permeability and inflammation. It also delivers human milk oligosaccharides in high concentrations, shaping the gut microbiome and preventing pathogens from attaching to the intestinal wall.
This window is brief. Once the colostrum phase passes, it cannot be recreated.
Those first drops matter.
