A. dear mum , for a baby who was born premature , low birth wt then the catchup growth can take time so u shd follow the growth curve with the pediatrician focus on healthy energy nutrient dense legumes dal beans / egg non veg , curd paneer , sweetpotato banana add powdered nuts to food avoid high sugar foods
