Hello Doctor My son with age of 10 months. He will get sick for a small weather change or climate change or water change. From long time, we are using Nasoclear drops daily 3 times. We are using this from the birth time onwards. His nose is blocking, So is this will result a long time problem. He has cold quite occasionally.

Is their a better way to improve the digestion and immunity strength for a 10 months kids.
