Although breast milk is the best feeding choice for babies, infant formula is fortified with nutritionally adequate ingredients. If you make the choice to bottle feed your infant, there are just three essential things that you need:  Baby bottles, your Natalplex Infant Formula and equipment to sterilise both water and your baby bottles and teats.

When introducing your baby into infant formula, do not be alarmed your baby is still getting used to the change so it is normal that she may suffer from infant constipation.


When choosing a bottle for your infant, please consider:

  • They have leak-proof caps, discs and teats
  • As glass bottles break easily, plastic bottles are preferred
  • Choose a bottle which is smooth on the inside. This will allow you to clean the bottle easily therefore, making it safer to use.
  • Bottles with clearly market measurement guides that won’t wear out over time.


When choosing a teat for your infant, please consider:

  • Flow rate – Most teats are labelled according to age; ensure that the teat you choose is correct for the age of your baby. Test the teat by holding the bottle upside down; the milk should drip out at a steady yet constant rate. If the teat drips slowly, your baby will get tired before you finishing feeding. If a stream flows through the teat, your baby will dribble during the feed.
  • Teat shape – a lot of teats are available claiming to be the exact replica of a mother’s nipple in the baby’s mouth. This is not true as none have proved to be of any particular advantage. Even ‘orthodontic’ teats have shown to be no better than regular teats; suggesting that later on they are not recommended for tooth development. With time comes experience, so eventually you’ll discover which teat is best suited for your baby.
  • Time – Your baby should roughly take about 15 to 30 minutes to drink a bottle of milk.
  • Air – Air bubbles should rise through the milk as your baby drinks. If you notice that the teat flattens whilst feeding, loosen the cap a little to allow air to enter the bottle.

Sterilising Equipment

Sterilising your baby’s equipment is very important. Up until 12 months of age, your baby’s bottle-feeding equipment must be sterilised. When cleaning your baby’s bottles consider the following:

  1. Wash all equipment in warm, soapy water
  2. Using a clean bottlebrush, remove all traces of milk inside the bottle
  3. Rinse thoroughly
  4. Sterilise

There are many different methods to properly sterilise bottle feeding equipment. Boiling is the preferred option but you may also choose from steam sterilisers which plug into a power point or microwaveable sterilisers which are specifically designed to do the job using your microwave oven.
