Bottles are made from a variety of materials: plastic, silicone, glass, and even stainless steel. Plastic bottles are lightweight and inexpensive. Some bottles require disposable plastic bag liners, which aid in cleaning, but require regular purchase of plastic bags.
Parents have a variety of safe options when choosing the water to use to mix formula. The two safest options are boiled tap water that has been cooled to room temperature or any type of bottled water. If tap water is your primary water source for formula, use bottled water occasionally to reduce fluoride exposure.
Bottled water must have a sodium content of less than 20 milligrams per liter. This level will be clearly marked on the bottle as "Sodium" or "Na," so always check before buying. Evian and Volvic are two suitable brands. The water must still be boiled before use.
