Baby Bottles Buying Guide

What to think about and how to go about choosing the perfect bottle for your baby.

When it comes to choosing a bottle for your baby – either to feed them breast milk or formula – you’ll want to find one that is as close to perfect as possible, so that the transition to bottle-feeding can be a stress-free experience for both of you. We’ve highlighted what to consider and some of our favourite bottles on offer, to help you make a decision quickly and easily. Ready to buy some bottles? Let’s go!

Obviously, one of the first things you’ll want to consider when choosing a bottle is whether the size is right for your baby right now. Size and flow are usually related, so the smaller the bottle, the slower the flow. Newborns generally need the smallest size and the slowest flow – once babies can suck more easily and need to drink more, they will graduate to bigger sizes.
Shape and design
There are two main choices here: straight necks and angle necks. Straight neck bottles are the traditional choice, but angled bottles allow the teat of the bottle to remain filled with liquid and free of air bubbles, which is helpful as it minimises how much air can be gulped in with the milk. Taking in too much air while feeding is one possible cause of colic. They are also thought to help with holding the baby’s head in an upright position – which may prevent ear infections. Unfortunately, anti-colic bottles aren’t guaranteed to reduce the symptoms of colic in all babies, and they can be tricky to keep clean. 

When it comes to what the bottle is made from, your choices are simple: plastic, glass and stainless steel.
  • Plastic is obviously unbreakable but it will deteriorate from being used so often.
  • Although glass baby bottles are made from heat-resistant, toughened glass, they can still break or get chipped and cracked. The biggest advantage of glass bottles is that breast milk can be safely stored in them – not the case for plastic bottles. Recent research found that a chemical bisphenol-A (BPA) can leach into baby food when plastic bottles with milk residue are heated at boiling temperatures for 20 to 30 minutes. It’s really important to look for bottles that are BPA free if you choose plastic bottles. Disposable bottles are a short-term solution if you’re travelling – they are ready-sterilised and come with a teat and a lid, so they’re very convenient.
  • Stainless steel bottles are not very common, but they are lightweight and unbreakable, and guaranteed to be non-leaching and free from BPA, pthalate, lead and toxins.
What makes a perfect teat? Good question! In general, experts agree that a good amount of flow and less air are the key points to look out for.
  • Each baby is different, of course, and you can choose the speed of the flow – slow, fast, medium and variable – to make your baby’s drinking easy. It’s generally a good idea to start with slow flow for newborns, then switch to medium flow and only graduate to fast flow when you know your baby can suck fast enough. If you find your baby choking, spluttering, or if you see milk leaking from their mouth, it’s a sign that the flow of the bottle is too fast.
  • You can choose a standard teat shape or a natural one (which mimics the shape of nipple to make the transition from breast to bottle easier).  
  • Another consideration is what material the teat is made from: silicone is generally thought to be better than latex because it lasts longer and it is safer, but it is a little less flexible.

Top tip
When buying a bottle, it’s a good idea to get all the necessary accessories that help with cleaning, storing and carrying them. You’ll need to sterilise the bottles regularly – either with a microwave or an electric steam steriliser. Electric steam sterilisers can hold up to six bottles at a time and sterilise all of them in under ten minutes. Sterilising in the microwave involves putting the bottles in a simple container that you put in the microwave.

Avent BPA-free Bottles
These BPA-free bottles come in three sizes – 125ml, 260ml and 330ml – and five different flow rates.
