Girls, help ? I called the doctor, but she said she'll come only when it's free ? My son is 38.3. Gave him Ibuprofen. I don't know what to do, I'm panicking? It was all good in the morning, but after the first nap he woke up crying and keeps crying. There were some mucus, but I thought they might be from crying ? The stool was not like usual - thick. I can't tell if his cheeks are swollen or not because I don't know how they should look when swollen and he doesn't let me see properly. Has anyone experienced this? Toothache or cold?? I haven't encountered either of them so
