Making the bottle(s)
Once you have chosen your formula, you will now need to know how to prepare it correctly. If your baby has had formula from birth, you were probably shown how to prepare this in the hospital. However, many women will start to use formula after they go home, and may not be aware of the procedures involved.
A tin of formula usually comes in a powdered form. Check the date on the bottom of the formula tin to make sure it is not past its 'use by' date. Once the tin is opened, the formula needs to be used within one month. So, if you are only supplementing your baby occasionally with formula, you are best to only buy small tins.
The formula needs to be prepared exactly as recommended, to give your baby a balanced nutritional diet. Adding extra powder to make the formula 'richer' is dangerous and can constipate and dehydrate the baby, making them sick. It may also make them put on excessive weight. Diluting, or 'watering down', the formula will mean your baby is not getting enough. They get sick and vomit and not put on weight. Therefore, it is important that the correct measure of powder is added to the correct amount of water. If you think your baby needs 'more' just make up more milk, as directed on the tin.
Some women will just prepare each bottle as they need it, others will make up about 6 to 8 bottles at any one time, to last them about 24 hours. Any pre-made bottles of milk need to be refrigerated until needed, and used within 24 hours after being made. You will need to discard any milk not used in this time.
