I breastfed all my babies, didn't use bottles. When we did foster care, all our babies had glass bottles. I bought Gerber glass bottles. Plastic isn't healthy, especially in food consumption. Anyway we can scale back the amounts of plastic used in daily living, the better, and safer for our children with developing immune systems. We don't eat off plastic, not do we store leftovers in plastic. Glass containers and jars are prefect for food storage. Babies should have limited contact with plastics, at least controlling what is possible, is doable.... This includes toys.
