Baby formula has been hard to find in many parts of the U.S. for months, sending parents searching for Enfamil, Similac, Gerber and other brands.
Retailers and formula makers agree that out-of-stocks are a problem. They don’t agree on how severe it is and who is to blame. Chains like Walmart Inc. and CVS Health Corp. say the manufacturers are having supply issues; formula makers say retailers aren’t getting product to stores once it is delivered.
