First time baby being sick… Need advice

🤰🏻

So im a FTM. Last night my baby was coughing a lot and this morning she just seems like she has a cold. Congested, cough, when she breaths you can tell shes sick. I never had a sick baby before so I don’t know what to do to help her? She doesn’t have a fever so that’s good. Ive been sucking her snot with my frida sucker but thats all I can really do I think.

Any advice. Shes 4.5 months old.
