How much formula milk does my baby need?

How much formula milk your baby needs can easily be worked out using a simple formula; your baby needs approximately 150-200 ml of formula milk per day per kg of your baby’s weight. I have made this easy for you to work out;  my quick formula feeding quantity guide below. (Please note that this is a guide only, you should always feed your baby when she seems hungry and have her weighed regularly to check her progress).

You will also find a formula quantity guide on the side of your packet of infant formula milk. Bear in mind that your baby’s appetite can vary from feed to feed and from day to day. You should never force feed your baby, even if there is only a little bit of milk left. If you would like to work out how much formula your baby might need for a weight that is not listed above, multiply his weight in kg by either 150(minimum) or 200(maximum), this gives you the amount of recommended formula milk per day for your baby’s weight. To then work out how much milk he will need per bottle, divide this amount by the number of feeds he has in a day. This gives you the recommended amount of formula milk per bottle feed for your baby’s current weight.
