Girls, the child got sick on the 18th of the month, one day with a temperature. Two days without fever, then it rose again to 37.7. Again without fever, they were at the pediatrician this morning. She said everything is clean and the analyzes are calm. But there are still green specks. They came home again with a temperature of 37.4. Why? Or should we not pay attention to it anymore? Maybe someone had it like that?
