My 5 month old has RSV at this very moment actually. My husband came down with a horrible "cold" a few weeks ago (which lasted 2 weeks), so I kept him and our son as far apart as humanly possible living under the same roof, and also upped my vitamin C and elderberry intake (hoping to boost our sons as well, since I'm breastfeeding...) Try as I may to prevent him from getting sick, he came down with the same "cold" that we recently found out was RSV from his pediatrician... totally heart shattering. At the time, I'd heard of RSV, but not so much the specifics... it has been a very exhausting 9 days so far... it DOES get very scary at times, especially at night when he can barely sleep because of the horrible coughing and congestion... ugh. His pediatrician said that as a rule she generally hospitalizes an infant under 6 months because of the serious risks associated, but because he is breastfeeding she feels it's not coming down as hard on him. We brought home a Nebulizer just in case it got really out of control. RSV is also notorious for causing ear infections; our son had infections in both ears! Poor baby...
I inevitably got sick as well a few days after DS, and firsthand I can say it's no walk in the park... I got my first ear infection that I can truly ever remember in my lifetime. Fortunately, the last couple of days have been MUCH better and DS is his happy, cuddly, lovable, smiling self again. I felt so helpless and miserable seeing him suffer, hands down the hardest thing I've ever had to endure.
I'll be glad when this whole experience is just a very distant, distant memory... soon, soon.
