A. Your child is practically not gaining any weight I’ll tell you the basic funda behind calculating weight is 500 g in a month should be seen so your child has only gained about 400 g and almost 2 months which is not meeting the minimal criteria also so it’s very important that you please check with your doctor and start giving formula to the child for better growth and gain of your child
