What should I do to make my baby's skin glowing?

I am sure your baby skin already be glowing. All you need to do is feed him well. If he is on breastfeed he will get all the nutrition from your milk and if he is on solid diet, feed him everything home cooked. Paneer, soup, veggies, pulses, fruits, curd, etc. You can do him massage daily and it will make his muscles and bones strong. You just have to take care of his overall health and when that is fine, there will be glow from within.
