The ETHICAL NUTRIENTS company sells an INFANT/NURSING MOTHER formula of BIFIDUS INFANTUM probiotics, called DAIRY-FREE, MAXI-BIFIDUS, that has only rice maltodextrin (supposedly gluten-free) mixed with
the Bifidus infantum powder. This is a milk-free preparation, and can be
very helpful to treat or prevent yeast infections (like Candida albicans/thrush, etc.) in a baby that took anti-biotics. Look in the refrigerated section of good health food stores.
