#AskTheExpert Hello , my son is 3 years and 11 months old. From past 2 weeks he is having nasal congestion at night.he wakes up alot and sit during night due to trouble breathing. he has itchy eyes, nose and he sneezes alot in day time.he breaths from mouth during day and when i ask him to breath from nose, he tries but it is not smooth. I am his mother and i have allergic rhinitis. What should i do ?
