Thanks [/INST] Hello. Thank you for asking at Chat Doctor. I went through your history. I think your daughter has allergic respiratory problem, but I would like to ask more questions about nature of cough, cold, whether she wheezes, frequency of symptoms etc. to know exact nature of her disorder. However, for allergic respiratory diseases, I would suggest her Montelukast whenever she develops symptoms. This will reduce her symptoms along with other medications prescribed by your pediatrician. If she is having problems during any specific season, I would suggest to start daily Montelukast 2 weeks before the season and continue during the season. This will also reduce the number of episodes. I would suggest you to avoid exposure to dusts, smoke and air pollution as much as possible. Limiting foods that usually trigger her episodes will also help. Childhood allergic respiratory disorders usually can improve by ages of 6-8 years, but it depends on type of allergy she has, her diet and environment, hereditary factors, genetics, etc. So It's difficult to predict most of the time. I would also suggest you to consult an Allergist who will suggest her allergy testing and help you identify what to avoid and how to. Hope this will be helpful to you. Wish your daughter the best of the health. Regards. </s>
