Formula may be hard to find due to COVID-19. Many stores have low supplies of infant formula because people are over-buying or stockpiling formula. The amount of formula being produced remains the same. There is not a manufacturing problem.
You may have heard about formula companies sending free formula when you call the 800 number on the can. This is a false rumor that has been spread online.
Enfamil has responded to the false rumor with this statement,"Contrary to rumors in some online social networks, we are not distributing free cases of formula. We are instead focused on ensuring equitable availability for every baby."
In order to help with finding Enfamil formula, you can find stores that sell Enfamil here.
