Best Baby Bottles for Newborns - Glass, Stainless Steel, Plastic or Silicone? 5

The most common bottles for newborns are plastic ones. Even though they are more practical than glass and are easily accessible, plastic bottles are not all the same. Currently, there are three types of plastic feeding bottles in the market namely PP, PES and PPSU. If it is not indicated on the packaging, then it is most likely to be PP by default.

Unfortunately, some plastic bottles have a tendency to leach. With frequent sterilizing in high temperatures, the plastic components breakdown over time and release harmful chemicals into the milk your baby drinks.

Here are the 3 plastic bottles for newborns currently in the market:

PP (Polypropylene)

  • the most common plastic feeding bottle.
  • durable, flexible and economical.
  • available in clear and colour-tinted transparency.
  • can withstand the heat of up to 120°C.
  • may lose transparency over time with frequent sterilization and exposure to boiling water.
  • advisable to change once every 6 months or when there a change in the bottle’s texture.

PPSU (Polyphenylsulfone)

  • highest performing thermoplastic compared to PP and PES. 
  • able to absorb impact.
  • stain-resistant and odour resistant.
  • naturally BPA free.
  • has a high melting point of 208°C. 
  • commonly used in aerospace / medical devices that require repeated sterilization. 
  • more expensive than PP and PES bottles.
  • advisable to change bottles yearly.

Tritan

  • does not contain bisphenol A (BPA) or other bisphenol compounds, such as bisphenol S (BPS).
  • has no estrogenic(EA-free) or androgenic activity (AA-free).

With so many contradicting studies on the safety of plastics, manufacturers are now turning to silicone as a safer material to produce bottles for newborns. Here’s why parents should be choosing silicone bottles:

  • medical-grade, BPA-free and non-toxic.
  • does not contain phthalates, lead and PVC.
  • flexible and provides the infant with a more natural feeding experience.
  • scratch-resistant.
  • very heat resistant and can be safely heated in dishwashers, boiling water, sterilizers and microwaves.
  • Includes anti-colic vents and allows gentle squeeze which aids feeding.
  • easy for baby to hold and lightweight.
  • skin-like texture which could help with nipple confusion.

Making the Right Decision

Ultimately, parents should decide among the safer options when it comes to choosing bottles for newborns. Find one that meets your budget and your needs. Don’t be in a hurry to commit to one brand because some babies can be finicky with their preferences. Purchase one or two to try first and only invest when your baby has decided so as not to ruin your grand plan of having the perfect stash of bottles.
