A. No mam the weight seems to be quite less let me tell you this thing two things you should know that we expect a child to gain minimum of 500 g in a month and according to that you should evaluate your child should be at least 4 1/2 kg more than the birth otherwise generally standard if we look at it should be at least somewhere around 8 kg
