The safest way to prepare powdered formula milk is by using water that is boiled freshly in a kettle and is at least 70oC. Research by First Steps Nutrition Trust has shown that when 1 litre of water is boiled in a kettle if it is used within 30 minutes it will remain above 70oC.
It is important that all bottles and teats are washed and sterilised between every feed. Also, surfaces used for preparation should be cleaned and good hand hygiene is maintained.
The water should always be placed first into the bottle before the formula is added, always following the manufacturer instructions. The bottle then needs to be shaken gently and cooled to a temperature suitable for the baby to drink, either by holding the bottle under cold running water or standing it in a bowl of cold water. We do not recommend the use of rapid cooling devices or formula prep machines because the water isn’t the correct temperature when mixed with the milk. Before giving the milk to the baby, test the temperature with a few drops on the inside of the wrist.

As health visitors, it’s important that when we discuss infant formula with parents, we don’t recommend any brand, however, we advise that first milk is used until the age of one. Follow-on milk is not required as babies can move onto cow’s milk from 1 year of age. Adhering to this ensures that we are following the UNICEF International Code of Marketing of Breastmilk Substitutes Resources. We are bound to follow this guidance because we are Accredited as Baby friendly.
