California will become the first state in the nation to provide infants with hundreds of free diapers before they leave hospitals after birth. Officials say the goal is to ease the financial burden on families welcoming newborns in the notoriously costly state. The state will provide 400 diapers to each newborn through participating hospitals. The program in its first year will be limited to hospitals largely serving low-income patients, and then it will expand statewide after that. It comes two years after Tennessee and Delaware became the first states to offer free diapers to families enrolled in their state's Medicaid programs.
