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). What type of feeding bottle is best? Some parents are cautious about using latex teats due to the risk of developing a latex allergy, particularly if there is a family history of allergy to latex (Kimata, 2004). Wood, C. T., Skinner, A. C., Yin, H. S., Rothman, R. L., Sanders, L. M., Delamater, A., Ravanbakht, S. N., & Perrin, E. M. (2016). Association Between Bottle Size and Formula Intake in 2-Month-Old Infants.

European Commission (2011) Bisphenol A: EU ban on baby bottles to enter into force tomorrow. Available at https://ec.europa.eu/commission/presscorner/detail/en/IP_11_664 [Accessed 3 December 2021] You may hear that you should keep the teat full of milk to avoid swallowing air. However where the milk flow is too fast and not in your baby's control, it is more likely to cause indigestion or gas (Kellymom, 2020). Anecdotally, babies whose parents use paced feeding suffer less from gas (Herman, 2021). 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 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).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.

Bottles come in two sizes, small ones which hold 150mls (5 fl oz) and large ones which hold 250ml (9 fl oz). For the first few weeks, newborns feed little and often because their stomachs are so small (Unicef, 2019). The smaller bottles are more suitable for this period. Babies who feed from larger bottles consume more milk, which may lead to overfeeding (Wood et al, 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).
