My 8 month old, HELP

Cat Von Gee • Mother of 2 beautiful boys!

Hey guys!

My baby recently got sick. I think it was last Thursday and I took him to the ER on Saturday. Doctors told me he had really bad infection in his throat. He had a really bad cough and fever and I think his stomach hurted because he made signs he wanted to puke but didnt. He only puked once. They gave him an antibiotic shot and atibiotics to take orally and ibuprofen for the fever. Well his cough has gotten a bit better by now and the fever has been gone, but the only thing that I'm worried about now it's that he's had really bad diarrhea since like monday. He even got a really bad diaper rash because he's going too much and I think it's irritating his skin!

Is that okay/normal or should I be worried and take him to the ER again?
