Question: My baby is 2 months old and exclusively breastfed. His birth weight was 3.5 kg, and now he weighs 6 kg. Is this weight gain normal and healthy?

Answer: Good morning! You’re wondering if your baby’s weight is okay.

Weight Check * Birth weight (BW): 3.5 kg * Weight at 2 months: 6 kg * Feeding: Exclusive breastfeeding

✅ Yes, your baby’s weight is very good! Babies usually double their birth weight by 4–6 months, and your baby is growing well.

What to Do?

✅ Keep exclusive breastfeeding—it’s the best for growth. ✅ Monitor wet diapers (at least 5–6 per day) to ensure good hydration. ✅ If weight gain slows down later, check feeding patterns with a doctor.

You’re doing a great job! Keep it up! 💙
