Hi, My daughter is 1month 24days old.Her birth weight is 2.1kg. How much should she gain at the end of 2nd month?

A. 1 kg kilogram more than the birth which should be there because it is expected for a child to gain 500 g in a month so on that piece you can just add 1 kg to the weight that you have mentioned and that is the minimum weight gain by the age of two months complete
