Do you remember when the stomach upsets at night first started? Â If it was after you started feeding him solids, then he's more than likely allergic to something you feed him. Â If it's always been the case, then he could be allergic to something you eat through your breast milk or he has a serious GI issue. Â
Â
Do you ever give him anything with gluten? Â The first thought that sprang to mind when I read your post was celiac disease:Â http://kidshealth.org/parent/medical/allergies/celiac_disease.html#

It definitely doesn't sound normal, but I can't tell for certain what it could be from what you've written. Â Babies who eat a good amount of solids (like yours) should have solid poop, very rarely runny/goopy poop. Â Tummy aches every night is also a sign that he's allergic to something he's eating. Â I would eliminate any dairy or gluten, both from his diet and yours and see if that helps. Â Also, eggs are said to be THE most common food allergy in children, so I highly recommend eliminating that as well. Â If you take him to a pediatrician, be prepared for them probably wanting to do a blood test.
