 Two of the nation's largest baby bottle manufacturers are on the business end of class action lawsuits. Philips is one company, Handicraft is the other. It's the maker of the brand Dr. Brown's Baby. The plaintiffs allege that both companies knew their baby bottles were made using microplastics that can leak when heated, seeping directly into the baby's food or drink. The suit also alleges that both companies were aware of the dangers but still labeled their products BPA-free.
