Baby Feed Time Calculator calculates an estimate of how many ounces that you should be feeding your baby. The calculation is based on the number of hours between feedings and the weight of your baby. Since some babies need more and others need less there is a high estimate and a low estimate. The calculation is a guide to help you. It is especially helpful to use when increasing the number of hours between feedings so that you can make sure that you are still giving your baby enough to eat.
