For babies who have been diagnosed with rsv...

I took my son to his doctor for the bad cough he had on Monday and she said he sounded great but his oxygen level was just a little low. She told me what to look out for and he isn’t really doing the grunt or his stomach isn’t really sinking in far but I can’t tell if he is just stuffed up or if he is beginning to have a hard time breathing. I’m getting a bit nervous about it. I don’t know if I’m being paranoid. His breathing isn’t that loud so that makes me nervous because irk if he is pausing or if he is actually breathing through his sinus. And when I have him on the floor to watch and listen, he is all over the place... once again, making me feel a bit paranoid or if something is actually happening. 🤦🏻‍♀️ I never dealt with this with my other two kids.
