WASHINGTON (AP) — President Joe Biden is stepping up his administration’s response to a nationwide baby formula shortage that has forced frenzied parents into online groups to swap and sell to each other to keep their babies fed. The White House says Biden spoke Thursday with executives from manufacturers Reckitt and Gerber about how they could increase production and how his administration could help. And he talked with leaders from Walmart and Target about how to restock shelves. The shortage stems from supply chain disruptions and a safety recall. Retailers are limiting what customers can buy, and doctors are urging parents to contact food banks, physicians’ offices as well as warning against watered-down formula or making DIY recipes.
