Sure! You might have food allergies or intolerances, which can make certain foods cause problems like stomach aches, rashes, or trouble breathing. These happen because your body mistakenly thinks some foods are harmful. The best thing to do is avoid these trigger foods. An allergist can help you find out which foods to avoid and how to manage your symptoms.

A gastroenterologist should also be seen if pain under the left or right rib is present, because many gastrointestinal disorders may cause pain as a symptom of pancreatitis, gallbladder disease and gastritis.

I advise you to take your child to a doctor. Based on proper evaluation and diagnosis, the doctor will be able to determine whether the problem faced is due some underlying medical issue such as food intolerance, infection  or some other reason. Based on that, treatment may be suggested which may include certain dietary and lifestyle changes, medications etc. 

Having diarrhea or soft poop could be due to many things such as infections or food sensitivities while difficulty passing stool could mean constipation. You need to eat more fiber, drink plenty of water, and also go for a medical check-up to know exactly what is wrong with you.
