How bad was it when your baby had rsv for the first time ? How long did it last? What we’re all the major symptoms? I think my 5 month old has rsv but not 100% sure. We have a doc appt today. Last night the symptoms started. She was very congested and little bit of sneezing. No fever, just good amount of mucus. She didn’t have a runny nose or anything, I couldn’t really see any mucus when I looked inside her nose so the mucus was far back in her nasal. She only wanted to sleep in my arms, screamed when I set her down. Does this sound like it could be rsv?
