21 month old with rsv

Ka

Anyone with a 1 1/2 year old with rsv? What was your experience? My son on Sunday started coughing and throughout Sunday night and into Monday morning got progressively worse fast, fever of 102, lethargic, fast belly breathing. So I took him to urgent care. They diagnosed him with rsv without a test because there is a shortage but his flu and Covid test were negative. Today he is fever free (day 3 of symptoms) just snotty and coughing. Little bit of belly breathing but he’s eating and drinking. I guess my question is does it get worse from here or will he slowly be getting better. Urgent care wasn’t concerned with his fast belly breathing because his o2 was good.
