My baby is 4months old and she drinks very less milk and that too in less quantities throughout the day. She is not gaining enough weight. Doctor said try to feed her more milk but she vomits if forcefully fed or cries uncontrollably. Now I have started solids ( cerelac/barley/ dal puree) . Now she drinks the whole bottle milk as she is thirsty after taking solids. She sleeps better now and plays a lot too. Should I continue giving solids or should I not as we should not introduce solids before 6 months?
