If you are mixed feeding (feeding from both bottle and breast) it may help to choose a teat that will encourage your baby to open their mouth wide and take in the whole teat rather than just the tip. Those with a medium wide base and a short to medium nipple length encourage babies to open their mouth wide and cup their tongue around the teat (Pearson-Glaze 2019, Bahr 2010). This article describes it well. When should I change bottle teat size? It’s also recommended that babies stop drinking from bottles with teats by the time they are one year old as drinking through a teat leaves the teeth coated in milk and can lead to tooth decay (NHS Choices, 2015; Oral Health Foundation, 2017). Read more about this here. Since 2011, the European Commission has banned the use of Bisphenol A (BPA) in baby bottles. This was due to concerns that the chemical could leach out of the plastic and be absorbed by babies. None of the bottles for sale in the UK should have BPA (NCT, 2011).

On the other hand, they can take more space in a steriliser so you probably won’t be able to clean as many bottles at once (Which? 2019). Ready-to-feed bottles Parents who bottle feed find that they may need to move onto using larger bottles as their baby grows and milk consumption increases. Every baby is different so there isn’t a set age for when this should happen (Unicef, 2019). It’s important to follow your baby’s feeding cues and signs that they need more milk, such as finishing each feed and seeming to want more (NHS, 2015; Unicef, 2016).

Once they’re older and used to bottle-feeding, you could move to a medium flow. Just follow your baby’s lead to see what teat is right for them. Some babies prefer to stay on the slow flow teats for many months. You can also buy variflow teats where the flow rate can be varied by changing the angle of the teat (Which? 2019). You might find attending one of our Early Days groups helpful as they give you the opportunity to explore different approaches to important parenting issues with a qualified group leader and other new parents in your area. The MAM nipple is easily accepted by 94%* of babies thanks to its SkinSoft™ silicone surface and its unique flat shape, which feel so familiar to babies. This facilitates a switching between breast- and bottlefeeding.These bottles are shorter and fatter than the basic ones but you can put the same amount of milk in them. They usually come with silicone rather than latex teats and have a self-sealing lid. If you’re planning to breastfeed it isn't necessary to buy bottles ‘just in case’. Over 90% of maternity units in the UK are now Baby Friendly Accredited, which means a midwife on the infant feeding team should be able to support you if you do have any difficulties with breastfeeding straight after birth (UNICEF 2017). They’ll help you with hand-expressing your colostrum and feeding it to your baby using a spoon, syringe or feeding cup (Unicef 2017). Find out whether your maternity unit is accredited here. Many parents want to know ‘which brand of baby bottle is best?’ The fact is there is no independent research showing differences in feeding ability or pattern from different brands of bottles or teats (Which, 2021; Scheel, 2005). It’s down to you and your baby to see what works for you. Here’s an overview of the main types of bottles available on the market: Basic bottles When it comes to content, our aim is simple: every parent should have access to information they can trust.
