In most cases, you can feed your baby any brand of formula that is available. Contact your OB/GYN or pediatrician for guidance on adjusting feeding practices - some may have unused formula samples.
Visit hhs.gov/formula for information on milk and formula banks, WIC offices, and guidance from the American Academy of Pediatrics.
Do not water down formula, make formula at home, or discard formula unless it is expired or is part of the recall.
