my 2 older toddlers had rsv this week and unfortunately but inevitably the 3month old now has RSV. The dr explained what to watch for with retractions breathing issues and dehydration. I thought we were doing good with hydration as shes been nursing very well but she keeps getting gagged on all the phlegm and throwing up. I will work and work and work getting her to eat and then 15 or 20 min later she just throws it all back up. Yes I'm monitoring closely for dehydration somehow she must be keeping something in bc shes still having good wet diapers.
