Your Guide to Choosing Baby Bottles

Your Guide to Choosing Baby Bottles

When deciding what bottles to use to feed your baby, it is ideal to understand the different types of bottles available. Whether the bottles are filled with formula, breast milk or even water, here are some tips to help you choose the best bottles for your baby.

1. Plastic Baby Bottles (including BPA free)

Plastic bottles are the most common baby bottles available. When you are starting your baby on bottles, it is tempting to buy plastic bottles, as they are readily available, low cost, lightweight and durable.

However, there are some concerns over the safety of using plastic bottles. When a plastic bottle is used, some of the chemicals in the plastic can slowly seep into the milk, which are then ingested by your baby. This process is made worse when the bottle is heated up. 

Most plastic baby bottles will now be labelled as BPA free, as using BPA in baby bottles and sippy cups was phased out in 2010 as it was shown to be an endocrine disruptor.

However, it should be noted that even though BPA isn’t in baby bottles any more, it is often replaced with substitutes such as BPS and BPF which research shows has similar health effects as BPA.

Are plastic baby bottles safe?

If you have no other option than to use a plastic bottle, there are some steps you can take to minimise the risks. It is recommended to gently heat the milk in a glass or stainless steel container in the bottle warmer or under hot water first, and then transfer to the plastic bottle for feeding. Also it is best to discard scratched and old plastic bottles, as the risk of chemicals leaching is higher with a scratched bottle.

If your budget permits and you want a healthier and safer baby bottle, it would be ideal to avoid plastic baby bottles all together.

2. Glass Baby Bottles 

A safer baby bottle option is glass. Glass is non-toxic, doesn’t react with food materials and won’t leech anything into milk.  Glass bottles are more expensive than plastic, but they don’t need to be replaced as often as plastic making them a good investment.

Ecostork loves Lifefactory glass baby bottles made from high quality thermal shock-resistant borosilicate glass. The glass does not react with the content of the bottles, so no substances will get into the food. They are highly hygienic, due to the smooth and non-porous surface. These glass bottles are taste and odour free.

The bottles feature a protective silicone sleeve that helps prevent breakage and provides an easier grip. They are easy to clean - the bottle stays inside the silicone sleeve and goes straight into the dishwasher.

3. Stainless Steel Bottles

Food-grade stainless steel bottles are another option for families wanting to avoid plastic. Stainless steel bottles are durable, easy to clean and recyclable. They are a safe, healthy and toxin free baby bottle.

Stainless steel heats faster than plastic in hot water, which makes this bottle more convenient and safer for your baby.

4. Silicone Baby Bottles

Silicone baby bottles are gaining popularity amongst parents, as they are lightweight and safe to use. If you don’t like the feel of glass, then a silicone bottle might be the right choice for you. Silicone bottles have a soft texture and shape, which can provide a more comfortable grip.

Ecostork loves the Comotomo silicone baby bottle range. The patented design of the Comotomo baby bottle, closely mimics breastfeeding to reduce bottle rejection and nipple confusion issues. They are made from medical-grade silicone, proven to be safe and hygienic.

5. Nipple Material

Once you have decided what type of bottle you would like to use, the next step is to consider the nipples. Baby bottle nipples are commonly made of silicone, but there are also natural rubber options. Food-grade silicone is a safe, durable and hygienic material for baby bottle nipples. 

Whatever type of nipple you decided to use, we recommend that you inspect them prior to each feed and discard them at the first signs of damage.


Baby bottles come in a variety of shapes and sizes, and it is important to choose a bottle that works for both you and your baby. At Ecostork, we love the Lifefactory glass baby bottle range as we feel they offer a good mix of practical and eco features. They come with silicone teats and are easy to clean.

But if glass bottles do not appeal to you, then the Comotomo silicone baby bottle range might be a more suitable option. The ultra wide-neck design allows easy cleaning by hand (without the use of a brush) and the dual anti-colic vents prevent unwanted air-intake to help reduce instances of colic.
