My baby is sick for the first time 😭

My baby boy is 6 months old and I have tried so hard to keep him away from sickness but he now has his first cold. He has a slight cough and a stuffy nose. His cough isn’t worry some so far so I’m not thinking rsv. I just need advice on how to manage his cold. He’s my first baby and I just want to make sure I do everything right to help him. He doesn’t have a fever at all but if he does get one I sure will be bringing him to the doctor. But what are some tips you can give me as a first time mother dealing with a baby with a cold.
