Answer to Q8.
Always follow manufacturers' instructions to make up infant feeds. Most infant formulas are powders which must be mixed with cooled boiled water in the correct proportions. Under or overdilution will result in problems and could even be dangerous to baby's health.
Bottles too must be cleaned and sterilised very carefully.
It is very important that mothers receive adequate information in order to ensure the safe use of infant formulas. Manufacturers provide this information on labels and in product literature. Additional information should be sought from your health care provider.
