Please help, FTM with a sick baby

My 14mo has been sick with a cold since Monday. She has lots of snot/mucus, blocked nose, coughing. She wont let me suction her nose. She hasnt been eating. I dont know how to help her. Im a FTM and its the first time shes sick.

I have a humidifier in her room, i give her some tylenol when its bad. Im pushing water and milk to keep her hydrated.

What can I do to help her? I feel like its not getting any better at all and its been days!
