My 18month old has been vommiting off and on for 4 months now. I've taken her off of diary, which seemed to help but now she is vomitting again. This past week she caught a cold on top of it, has been coughing, running nose and tonight has rash on her cheek. I have had to give her zofran the last two days or she couldn't keep anything down. I have an appointment with a GI specialist but not for another week. Any ideas of what she could have? She's miserable and I feel helpless :(
