My daughter is 4 and she has been having diarrhea off and on since for almost a week.  Only in the middle of the night does she wake up and complain of a tummy ache and then throws up.  Usually mucus and a lot of dry heaving.  Not much food.  We have the humidifier going, elevated her bed, gave some allergy med. and in the middle of the night last night we gave her some peptobismal which she proceeded to throw up 20 min. later.  This all happened out of the blue and started 9 days ago.  In those nine days she has only slept through the night 3 nights.  We dont know what to do.  She is perfectly fine and her normal self during the day except for occasional diarrhea.  We have been to the dr. but they did not have much to tell us.  What is going on with our baby?
Dear parent, Does she have any fever? Is she going to pass motion after complaining pain in abdomen? Does her motion smell awful (than normal smell)? Then she has some infection of intestine. If she is vomiting mucus only check for respiratory infection. If these two are not there then check for worm infestation. Check what she is eating, if anything that she is eating is causing problem. Please check with your doctor again.
