my baby birth weight is 3.5 kg now she is 17 weeks old now how much weight she weigh please answer me?

A. It should be at least five kgs as of now because it is expected that the child should gain at least 500 g in a month so if I look at that exactly should be minimum of 1500 g and can be more than that when when we talk about least side should be 5 kg at least
