Please do not start any new supplements without a doctor's advice. Giving extra medicines without knowing the cause can strain your baby's system. Since she is already on Mediliv and Calcimax+ but not gaining weight, she needs a thorough evaluation by a pediatrician. The doctor will check her growth chart to rule out underlying issues like malabsorption, food intolerance, or silent infections. Instead of self-medicating, focus on offering small, frequent meals of calorie-dense natural foods like ragi, mashed bananas, khichdi with a little ghee, and continued breastfeeding or formula. Please consult her pediatrician for a safe, personalized evaluation.
