Gas trouble & bowel loops. Amul milk.

2 years son continuously suffering from Gas trouble since he was 5 days old he always suffers from pain mainly during night sometimes he does normal motion in a day though he suffers at night he constantly cries at night till morning due to stomach pain and gases are not easily released ! We have been using colicaid for pain and it helped a bit but from last 4 to 5 months even it seems its not working for him ! He rubs his stomach when he wakes up n cries ! We have done his abdominal scan as prescribed by a dr and it the results where that he has mild gases and dilated bowel loops with colonic content. Have been waiting for some useful and helpful medicine which will work for him he is on mother feed still as whenever we tried to introduce any milk he was suffering more so now we are introducing him amul milk. Thank you in advance.
