The Food and Drug Administration is doing everything it can to address a baby formula shortage, White House press secretary Jen Psaki said on Monday.

Up to 40% of baby formula is out of stock at U.S. retailers, up from 29% in March, and there appears to be no quick solution to the problem. The shutdown of a Michigan production facility with a history of compliance issues contributed to the shortage.

"They're working around the clock to address any possible shortage," Psaki said. "The FDA is taking a number of steps to address that, which includes working with major infant formula manufacturers to ensure they're increasing production."

Some retailers are limiting how much formula can be purchased at one time. Psaki spoke about the importance of formula and recalled buying it when her children were babies. Different kinds of formula are needed for different infants of varying age groups.

"Part of this issue is, of course, making sure there's stock on the shelves," she said. "We're working with the industry right now to optimize their supply lines, increase capacity, and prioritize product lines that are of the greatest needs."
