<s>[INST] We cloth diaper. We wash diapers about every three days. When I was prepping them for the wash I found a white round worm, with a taper tip, a black stripe on its body in my son s stool. I dont know if it came from him or not; the day I changed his diaper I didnt see anything. SInce finding the worm, we have realize that he has not poop for four days. Today he did but it was like pebbles. THis is not normal for him in any way. The last poop (coincidentally also the same diaper we found the worm) was very little, it was like he farted but poop came out also. He hasnt been sleeping well for about a week now, but we are in the middle of moving and thought it related to that. His anus has been quite red for awhile, but no worms or itching that we can tell. Could the worm in his diaper ordinated from our son, or could it have been larve in his diaper container? [/INST] Hi,It seems that your son might be having worm infestation, mostly round worm.Go for stool test for ova and cyst.Even without testing stool you can give one course of anti-worm treatment like Albendazole.Ok and take care. </s>
