Good day moms, could you please recommend a good syrup to help clear up macrota for a 2-year-old child with bronchitis? We were treated for two months ago, but she's been sick again, and she's all wheezing. The appointment with the doctor is only in two weeks. Drainage massage I do, but a good syrup would be helpful :)
