Before you begin bottle-feeding you’ll need to buy:
- A minimum of six baby bottles. Most babies feed around eight up to twelve times a day1,2, so if you're planning to bottle-feed, this will ensure you always have enough bottles to hand.
- At least six teats
- Equipment for sterilising
- A bottle-cleaning brush
- If formula feeding, your choice of infant milk
Baby bottles come in two sizes:
- Small 120ml/4oz bottles
- Large 225ml/8oz bottles
They are available in three widths:
There is no evidence suggesting one brand or type of bottle and teat is better than the rest1,3. Some makes of wide-neck bottle are specially designed to prevent your baby from taking in too much air, which can lead to wind and discomfort. An added advantage of a wide-neck is that they’re less messy when filling with formula or breast milk and easier to clean, but take more space in a steriliser and makes it challenging to sterilise many bottles at the same time.
You may find that regular bottles are easier to find teats for, are reasonably priced and are more likely to fit coolers and sterilisers.

Before you sterilise, ensure you clean the bottles and teats thoroughly using warm, soapy water and scrub them with a bottle-cleaning brush. You could also put them through the dishwasher5.
Once you’ve done this, there are three ways to sterilise your baby's feeding equipment:
- Steam sterilising – using an electric steam steriliser, or microwave sterilising
- Cold water sterilising
Teats come in all sorts of shapes, sizes and materials. The right type of teat for you and your baby will depend on your baby’s preference and the type of milk you are using. For newborns, it’s normally preferred to start with slow flowing teats, increasing the flow speed as your baby grows and gets used to sucking1.
If your baby chokes, splutters or leaks milk from their mouth during feeding it may be a sign that the flow is too fast – try a slower flowing teat. Again, if you think your baby is struggling with
