my baby is 15 months old ..her weight is only 8 kg..please suggest about her diet?

A. Hello mom by now the child should be used to regular foods made at home for the family now , kids by the age of 1 year they tend to triple their birth weight and then yearly they gain about 2 to 4 kgs if the baby was a preterm baby they tend to gain weight on a slow pace as compared to full term baby . they can be given dry fruits and nuts, seasonal fruits and vegetables, eggs , milk , panner , ghee , lentils and legumes, cereals and millets
