My baby drinks milk every 2 hours during the day. Sometimes he drinks every 1 1/2 hours. He is urinating properly. But he has not gained birth weight even after 20 days of birth. What can be done about it?

A. Namaste Mom, New born after birth in a few days initially they tend to lose weight and first they regain their birth weight and then on start to put on weight. Monthly weight gain is expected in the range of 400 gm to 1 kg .
