A. Hello mom Some babies don’t gain weight easily but in such cases if your baby is active and taking proper meals on time then everything is fine and nothing to worry about. If your baby is having any sort of pain in these veins then you should definitely consult with your doctor about it otherwise there is nothing to worry about
