Hello Doctor, Good Morning! My son is approx 2years old, precisely 23 months. He catches Cold and throat infection very fast, Doctor said few kids are prone to it you can start immunity boosters if you want. I don't want to go for allopathic medication for that. Can some one suggest me Homeopathy Immunity Booster for my son. Someone suggested BC28 or Mama Nature Munostim of Schwbe are good for kids for immunity boosters. But want some recommendations upon the same. Thank you so much in advance.
