My baby is 3 months old..his weight is 5.4 kg ...but still looks so weak especially his face ..what to do to make him chubby?

A. dear Mum, weight of 5.4 kg is a healthy weight for your 3 months old baby. do not go by the appearance of your baby. if your baby is active, alert, passing urine more than 7 times in 24 hours, achieving all growth milestones then it indicates good health. you should continue to exclusively breastfeed till 6 months complete for healthy weight gain.
