Some infants, probably. On a widespread general basis, probably not (yet?). Switching between different formulas for normal/healthy babies can be done (if a preferred brand is out of stock but something else is available), but it's not trivial. Switching to a different formula for a baby with special dietary needs, special allergies, etc., can range from "difficult" to "impossible." For those parents, this is an acute crisis, and "going hungry" doesn't begin to describe the potential impact; stunted development in the newborn phase, has long-term knock-on effects. Newborns are very different from adults (or even just, older children); adults can skip a few days worth of meals or ration their calorie intake for weeks, without much adverse long-term impact... newborns cannot do this.
