4 month old has RSV

I’m so upset. Just got back from the doctors office with my 4 month old, and she tested positive for RSV. I hardly ever go anywhere so I’m just kinda shocked that she got it at all. Anyone else have a young baby get RSV and it be okay? The doctor did say that she doesn’t think it’s gonna get much worse for her but of course I can’t help but think about the what if’s. I’m just so anxious about it all 😭

Edited to add: I do have some colostrum saved up, do y’all think giving her some would help this?
