Sick baby

C

Hi guys, I’m a FTM and this is the first time my baby has been sick so bear with me if my question is silly. He is 6.5 months old for reference. He has a stuffy/runny nose and is so congested.

He is also spitting up yellow - is this normal or something I should be concerned about?

Ive put a humidifier in his room, nursing him like crazy, sucking his nose out when he lets me, and I’ve given him some Coryzalia. Is there anything else I should be doing for him?
