A Texas-based pediatrician says not so fast with the homemade baby formula. Shortages of formula are forcing parents to get creative, and some are even sharing home recipes online. Dr. Valerie Smith says that can get dangerous. She says instead of going to the pantry, folks should call their pediatrician. Doctors can help get formula as a medical supply. The infant formula shortage started with a recall earlier this year and has been compounded by supply chain issues.
