A. Ma’am you can give milk with dry fruit powder with a pinch of black pepper and saffron and turmeric into that that is the best thing that Home remedy I can suggest you for a healthy immunity and generally if you can avoid giving more of junk and sugary fruits that also is going to benefit your child
