Pediatrics. Would be a great help.

Hello everyone. I am Satbir Singh. I have a son who is around eighteen months old. His name is Angad, so the thing with my son is that he started teething when he was merely 2 months old and since then he becomes easily diarrhetic. This problem has existed since he was 2 months and is continued to this date. The symptoms include dysentry and major dehydration. These problems recur every 1-2 months and last for atleast a week everytime which is very difficult for a kid so small. As a matter of fact he is still suffering from the same pattern again. He has been hospitalised twice for the very same condition. We have gone to a lot of doctors for help but nothing seems to be helping so a prescription or any solution would be a great help. Thank you.
