Help! My two month old is sick 🥺

Hello! I have a ten week old and last night around 11:45, she started vomiting a lot coupled with a wet cough. Started at the same time. She ended up vomiting once more around 3am and then no more after that. She’s been able to eat and hold it down since then.. her wet cough and runny nose are still here though. :( she’s been lethargic all day, basically just sleeping.

I called the doctor and he basically said to just wait it out. 🥺

Any tips or similar experiences? How long did it take for your LO to start feeling better?
