A few day sbefore halloween my son threw up at night then the day after halloween night he did again, At first i was thinking maybe to much candy even though he had hardly any. He acts totally fine during the day. But then every 2-3 days he will throw up at night, after ive put him to bed, i get him up in the morning to find out he puked in his bed again. A few days after halloween he got diarheea its not constant maybe 3-4 poopy diapers a day. So then i was thinking a food allergy but he hasnt had an change in his diet. Last night he threw up ,in his bed, tonight he did the same but i heard him and had to bathe him etc. Then i got to thinking, i just got a cat around the same time that he has been getting sick. So i was wondering if there is anything that would cause this random vomiting only at night and the diarhea. i feel bad he has such a bad rash from the pooping. I just ugh , i was about to drive to the hospital tonight but i couldnt get a hold of my friend to watch my daughter because its soooooo cold and snowy and wet outside so i didnt wanna drag both of em to the hospital. Bit i dunno it jus tmakes sense to me about the cat theory. But i cant seem to find anything online.
