Girls, how many kids are sick of you? We usually have almost no symptoms by day 5-6. Now they started going to kindergarten, got sick, after a week the doctor issued a certificate that the child is already healthy. We go for 2 hours only, I think it's possible to continue. Or keep at home for a while longer. There are residual phlegm somewhere in the nose, sometimes because of them they cough. It doesn't come out with any cleaning.
