But don't try to take matters into your own hands, moms. According to the New York Times, pediatricians "strongly advise" against trying to make baby formula at home.

Some are rationing food or driving to stores hours away only to find empty shelves. Others are heading online to look up homemade baby formula recipes that use anything from powdered goat's milk to raw cow's milk.

"Homemade formula is dangerous for babies," said Dr. Katie Lockwood, an attending physician at Children's Hospital of Philadelphia Primary Care. "Regular formula is F.D.A.-regulated and held to very high standards, the same way we treat medications. Making it at home is a lot riskier."

Steven Abrams, spokesman for the American Academy of Pediatrics, said "The nutrients in homemade formulas are inadequate in terms of the critical components babies need, especially protein and minerals."

Home brew baby formula can also contain "an excess of materials or nutrients, like salt, which a baby's developing kidneys or liver may be unable to break down."

What's more, babies can suffer from "water intoxication," - where the "baby might get too much water" if the balance of nutrients and liquids are off, according to Dr. Suzette Oyeku, chief of academic general pediatrics at the Children's Hospital at Montefiore, in New York City.

What's their solution? Call your doctor! Go to a charity! Use cow milk in a pinch!

"The first call any parent or caregiver struggling to track down baby formula should make is to their child's pediatrician. They may have formula samples on hand, or be able to help connect you with local charities or breast milk banks that can help."
