This will depend on how frequently you’re planning to use bottles to feed your baby. Newborn babies generally feed between 10 and 14 times in 24 hours, with feeds becoming a little less frequent as they grow. If you are exclusively bottle feeding your baby, whether formula or expressed breastmilk, you might want around four to six bottles and teats to get you started. This allows for sterilising them between feeds.

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? Allow bottle to cool down before removing from microwave. Recommended cooling time: 10 minutes at opened microwave door.

How many bottles and teats do I need?

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).

Safety is our number one priority for your family, and our bottles are easy to assemble, leak-proof, shatterproof, are BPA and BPS free and are manufactured in the EU. 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).

Bottle nipples

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). What type of feeding bottle is best? As a baby’s feeding develops and they are taking a longer time feeding from a Level 1 teat, many parents choose to move up to a Level 2 teat.

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] The MAM 0+/ 2-6+ Soothers are ideal up to the age of 6 months as they offer a smaller teat and shield for younger babies. The MAM 6+ Soothers are suitable from 6 months of age until one year as they provide a larger teat and shield than the 0+/ 2-6+ range but a smaller teat than MAM's 12+/ 16+ soother range. The MAM 12+/ 16+ Soothers being the largest of the MAM teats are ideal for older babies to use from 1 year of age until soother use stops.Herman (2021) How you offer a bottle can be more important than what’s inside, Available at https://www.todaysparent.com/baby/breastfeeding/paced-bottle-feeding/ [Accessed 6 December 2021] A Level 1 or newborn teat generally comes on every bottle and is a great starting point for many babies. With newborns, especially premature babies, the teat flow rate can actually be faster than your infant can tolerate. If your baby is exhibiting any of these signs while eating, you may want to try a slower flow (lower level) teat: NHS (2019b) Sterilising Baby Bottles, Available at https://www.nhs.uk/conditions/baby/breastfeeding-and-bottle-feeding/bottle-feeding/sterilising-baby-bottles/ [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). Knowing when to move to the next teat level is an important – and sometimes confusing – part of a comfortable and happy feeding experience for you and your baby. Wood, C. T., Skinner, A. C., Yin, H.
