Mothers’ Experiences with Plastic & Glass Bottles

Nadia Gamal, a mother to two children, 5 years-old and 18 months-old, uses the Avent Plastic bottles, as they are BPA-free. She says, “Although I know that glass bottles are healthier, they are impractical, and I cannot accept the idea of using glass around my baby.”

Menna Yehia, a mother to an 18-month-old, also uses the Avent bottles, in addition to the Tommee Tippie. She says, “I like the plastic bottles; glass could be dangerous.” Reham Medhat, a mother of a 2.5-year-old girl, said the same: “Glass bottles are healthier, but can be broken anytime.”

On the other hand, Hala Taher, a mother of an 18-months-old, thinks that glass bottles are the best choice: “Glass bottles are cleaner and you will not need to be changed every once in a while. I prefer Dr. Brown’s.” Nermin Ali, a mother of two (4 years-old and 5 months-old), agrees to Hala’s opinion and adds, “Glass bottles are better, but take care, they are also heavier, and can be easily broken if they fell.”

Aya Samy, the mother of one-year-old twins, also says, “For me, glass bottles are much cleaner than plastic bottles; the color of the plastic bottles changes with time.”

Now that we know the pros and cons, how do we choose?

Your choice will vary according to your need. This is why it’s necessary to define your needs first. Yaoota will help you with the purchase decision through a series of questions you can ask yourself:

  • How often will you need to heat the bottle?
    If you are formula-feeding, you will need to heat bottles more frequently, and thus will need glass bottles. However, if your use for the bottle is restricted to offering the pumped mother milk in it, you won’t actually need to heat it, and thus plastic bottles are more suitable for you.
  • What do you intend to use the bottle for?
    If you’re going to use it to feed the baby directly, it may be better to get a glass bottle. However, if most of your usage will be to store breast milk — especially in the deep freezer, which means you will repeatedly get the bottles in and out of the deep freezer, making them more prone to falls — it is better to use plastic bottles.
  • How old is your baby?
    If your baby is younger than one year-old, you will probably hold  the bottle for them as they drink, so you can safely use the glass bottles. However, if your baby is older, it is recommended that you use the plastic ones, which are both lighter and less prone to breaking in case of falls. 
  • Do you need a cheap or expensive type?
    If you are willing to purchase expensive bottles, but you worry that they may be broken, then it’s better to use the plastic type.

Now that we knew the pros and cons of each type and how to define our needs, Yaoota will tell you more about the most popular brands for each type.
