Glass baby bottles were once the norm. For the past few decades, parents have been opting for the more durable plastic bottles that can withstand the heat of modern dishwashers as well as an occasional drop on the floor. The trend is slowly moving back to glass bottles.
Glass bottles are a natural and safe alternative to plastic that may leach chemicals into the breast milk or baby formula, but they are not as easy to find. More manufacturers are making glass bottles because of higher demand in the past few years. You may have to order them online if you live in a smaller town.
Glass bottles are made of tempered glass. Tempered glass is two or more times stronger than normal glass. When broken, it shatters into many small fragments which prevent major injuries.
Glass bottles are available in 4 oz. (120 ml) or 8 oz. (240 ml) bottles. The sides of glass bottles are conveniently marked, allowing you to easily measure ounces and milliliters. Most glass bottles come with hard plastic nipple covers to keep the nipple clean when traveling. Glass bottles are dishwasher safe. Some are safe on the top rack only, so you will want to check the manufacturer's instructions.
Glass bottles and bottle nipples need to be sterilized before you use them for the first time. They must be washed thoroughly after each use with warm soapy water and a bottle brush. It is best to use a plastic bottle brush with glass bottles; wire bottle brushes can scratch a glass bottle and may cause the bottle to break or crack.
You can warm a glass bottle in a pan of hot water, hold the bottle under the tap, or you can use a bottle warmer. Never use a microwave to heat bottles. Always warm glass bottles gradually; sudden temperature changes can cause it to crack or break. To avoid shards of glass ending up inside the bottle and harming your baby, glass bottles with cracks and chips should be discarded immediately.
- I was a breast feeder, so I didn't have to use bottles very much. Surprisingly, I had one or two of a few different types of bottles and tried them all. My favorite glass bottle was the Classic Glass Nurser Bottle. I love the classic design with the moulded markers on the side to let you see how much your baby has consumed. The classic glass bottle was really what caught my attention, but they are really just good bottles. They are quite strong, are dishwasher safe, and they heat breast milk quickly when sitting in a glass of hot water. Overall, a nice strong, classic baby bottle.
