Hi yes it's absolutely normal for babies to skip food when they are ill. Keep making him take steam this will clear his nose and throat, give haldi milk, you can also give honey mixed with little pepper powder and turmeric powder. Give soups like dal soup, vegetable soup, chicken soup. Don't worry about his weight, its part of childhood.
