Hi moms, hello! How are you? Please help me — my child was born at 7 months, had fetal growth restriction (IUGR). Until he was one year old he was often sick, and then suddenly an allergy was identified (fur/dander, animals, dust, smells, mold) and something like bronchial asthma. The child is already 2 years old. We were treated with Pulmecord for 3 months but there are no results. When he runs even a little, coughing starts immediately for about 5 minutes. How to deal with this? Please recommend a good pulmonologist or someone else we can turn to, I don't know where to go anymore. City: Karaganda
