My daughter is not gaining weight and has very weak immune system...please help🙏#asktheexpert

A. hi dear Kids tend to get taller at a pretty steady pace, growing about 2.5 inches (6 to 7 centimeters) each year. When it comes to weight, kids gain about 4–7 lbs. (2–3 kg) per year until puberty starts. This is also a time when kids start to have feelings about how they look and how they're growing.
