Baby cold

What have you guys used for your little ones with colds? My daughter has caught one and she’s all congested, has a snotty nose, and just feels like crap. She’s starting to get a small cough now.😢 she just went to the doctor last week, I will probably be making another appointment if she gets any worse. But I just want to know of things you guys used or did. My poor girl is miserable. I hate this time of year because of all the sicknesses!
