My 3 yr old wakens pretty much every night around the same time, screaming, appears to be still sleeping and can't be pacified. He screams more if you touch him. He usually then farts a few times and cries some more then goes to sleep. I wondered was he in pain, as in trapped wind. Wonder what I cud do to help him. He has very regular bowel motions 2-3 times a day so it's not constipation and the motions appear normal. Any ideas?
