How many calories are there in a cup of milk for baby?

There is no such thing as "milk for baby". The question assumes that there is a particular type of milk specifically and exclusively produced for babies. There are different types of milk, including human milk, cow's milk, soy milk, almond milk, and others, each with different calorie content. For example, one cup (240 ml) of whole cow's milk typically provides about 149 calories, while one cup (240 ml) of breast milk provides about 170 calories.
