We discourage the use of cow's milk until a year of age but it's certainly true that as the baby is close to a year of age, especially if it's simply no formula to be found, that you could use either that or a toddler formula, neither are ideal, but the closer you are to the year, especially for the short term, those are alternatives.

We're not irrational. If there is nothing you can put in the baby's mouth except cow's milk, you're going to do that, but that's not what we want people to do.

There is a lot of discussion about making your own formula at home and things of that sort, and I really want to discourage that as much as possible.

It's a less-than-ideal alternative but if that's what they have to do, then that's what they have to do.

What we want people to do if at all possible is to be as flexible as possible and make formula switches.
