Baby Bottle

Glass vs. Plastic Baby Bottles

Decades ago, the only baby bottles available to parents were made of glass. But glass was heavy and, more importantly, breakable. So when plastic bottles came along that were lighter and shatter-proof, the glass bottle became almost obsolete.

However, recent reports that a type of plastic found in baby bottles might cause potentially harmful changes in developing babies has left parents wondering if perhaps old-fashioned glass wasn’t such a bad thing after all.

Which is safer, glass or plastic? Here is some background on baby bottles plus some tips on how to choose — and use — bottles safely and effectively.

Baby Bottle Worries

The problem with glass bottles is pretty obvious — drop one on the floor in the middle of a late-night feeding, and you’ll have a roomful of shattered glass to clean up. Glass is also heavy and cumbersome. On the upside, glass bottles are sturdy, and they don’t contain any chemicals that could potentially get into the baby’s formula.

Plastic baby bottles are lightweight, strong, and unbreakable. However, concerns have arisen about the polycarbonate type of plastic bottles because they contain a chemical called bisphenol A (also called BPA). Bisphenol A is also used in everything from compact discs to the lining of cans, as well as other consumer products. A 2007 report by the organization Environment California showed that when heated, five popular brands of BPA-containing plastic baby bottles leached high levels of bisphenol A.

In studies of lab rats, low levels of BPA were linked to changes in the brain and reproductive system that researchers say may contribute to an increased risk of prostate and breast cancers, ovarian cysts, endometriosis, and early puberty.

Before you panic, know that government health officials don’t believe that the amount of BPA in baby bottles and other consumer products is dangerous. After reviewing research on the plastic, the FDA stated that based on its ongoing review it believes the amounts of bisphenol A that find their way into food and drinks are too low to cause any real health effects in humans. However, the agency is continuing to look into the question of BPA safety, and for now, the issue remains unresolved.

Choosing a Baby Bottle

There are essentially three types of baby bottles: plastic, plastic with disposable liners, and glass.

Although the jury is still out on bisphenol A, if you want to avoid any bottles that contain it, look for the #7 recycling symbol or “PC” on the bottom. That’s usually a sign that the bottle contains BPA. However, not all plastics labeled with #7 recycling code contain BPA. Some bottle brands, such as Born Free, explicitly say that their products are not made of Bisphenol A.

The six major U.S. manufacturers of baby bottles and infant feeding cups have confirmed to the FDA that as of January 2009, they have not manufactured these products using BPA for the U.S. market.  These manufacturers represent more than 90% of the U.S. market.  These manufacturers produce brands that include Avent, Doctor Brown’s Natural Flow, Evenflow, First Essentials, Gerber, Munchkin, Nuk, and Playtex.    

Even if you’re concerned about bisphenol A, you don’t have to give up your plastic bottles. Non-polycarbonate plastic versions are available. They’re made of polyethylene (#1, #2, or #4 recycling symbols) or polypropylene (#5 recycling symbol). Non-polycarbonate plastics are also options when your child graduates to a sippy cup.

Disposable bottle liners are also typically BPA-free (look for the words “BPA-free” on the label). They tend to be more expensive than bottles alone, though, because you have to change them after each feeding.

If you want to try glass bottles but you’re concerned about them breaking, some companies make silicone sleeves that go over the bottle to protect it.

Caring for Your Child’s Baby Bottle

Here are some tips on caring for your child’s baby bottle and reducing potential risks from BPA:

  • Never store breast milk or formula in plastic bottles. Pour it into the bottle just before your baby is ready to eat. Throw out anything that is left over.
  • Heat and wear can both increase the rate at which BPA leaches out of the plastic. Heat polycarbonate bottles in warm water (not boiling), rather than in the microwave. Microwaves should also be avoided because of the risk of burning baby’s mouth. Throw out any polycarbonate bottles that are scratched or cracked.
  • Don’t use hot water or a harsh cleaner on polycarbonate bottles because this also can cause the plastic to break down more quickly. Instead, use a gentle cleaner and warm water.
  • Replace any glass bottles that have cracks or chips in them.

Keep in mind that bisphenol A is also found in the linings of formula cans and can get into the product. You might want to opt for powdered formulas, which typically contain lower levels of BPA than liquid formulas.

I am located in USA, specifically in Los Angeles, California. In 2008, I returned to Indonesia & Malaysia with my baby who was then aged 2 months. Like other moms, I brought suitcases full of baby items. My friends see the things I bring and they are interested in purchasing for their babies. Indeed, baby goods in United States is very modern, secure and very easy to use for moms. Because a lot of friends who asked me to deliver the goods to Indonesia, I started selling baby goods direct from United States. Indeed the cost of shipping from here to Indonesia & Malaysia is not cheap, but my customers feel the goods that they purchased are very useful and shipping costs are not an issue.

Fancybabyshop starts a business through word of mouth and from Facebook. Due to high demand for other goods as well, I decided to create a website, so that moms can easily order their desired goods.

Hopefully, can become one-stop-shop for moms as we are adding new goods to the website everyday. I’m trying to sell all goods needs for babies and moms. If there are goods that have not been listed in, you can send an email to and I will find such items for you.

Why breastfeeding is important?

Breastfeeding protects babies

  1. Early breast milk is liquid gold – Known as liquid gold, colostrum (coh-LOSS-trum) is the thick yellow first breast milk that you make during pregnancy and just after birth. This milk is very rich in nutrients and antibodies to protect your baby. Although your baby only gets a small amount of colostrum at each feeding, it matches the amount his or her tiny stomach can hold.
  2. Your breast milk changes as your baby grows – Colostrum changes into what is called mature milk. By the third to fifth day after birth, this mature breast milk has just the right amount of fat, sugar, water, and protein to help your baby continue to grow. It is a thinner type of milk than colostrum, but it provides all of the nutrients and antibodies your baby needs.
  3. Breast milk is easier to digest – For most babies — especially premature babies — breast milk is easier to digest than formula. The proteins in formula are made from cow’s milk and it takes time for babies’ stomachs to adjust to digesting them.
  4. Breast milk fights disease – The cells, hormones, and antibodies in breast milk protect babies from illness. This protection is unique; formula cannot match the chemical makeup of human breast milk. In fact, among formula-fed babies, ear infections and diarrhea are more common. Formula-fed babies also have higher risks of:
    • Necrotizing (nek-roh-TEYE-zing) enterocolitis (en-TUR-oh-coh-lyt-iss), a disease that affects the gastrointestinal tract in preterm infants.
    • Lower respiratory infections
    • Asthma
    • Obesity
    • Type 2 diabetes

    Some research shows that breastfeeding can also reduce the risk of Type 1 diabetes, childhood leukemia, and atopic dermatitis (a type of skin rash) in babies. Breastfeeding has also been shown to lower the risk of SIDS (sudden infant death syndrome).
