Baby has croup :(

Went to the drs today because my baby had what seemed like a bad cold and I thought she was wheezing. Turns out she has croup and an ear infection 😢😢

Please any advice welcome. I’m a ftm and it’s pretty scary it feels like she can’t breath. I’m following all my drs suggestions I’m just nervous. I’m going to sleep on the floor in her room tonight so I’m close to calm her down if she starts coughing bad. Ugh breaks my heart and has my anxiety sky high.
