Baby has a cough

I am of course calling the pediatrician as soon as they open.

Everyone in the house had sinus stuff the past few weeks, and LO had similar symptoms so I thought nothing of it. But he has a cough and is sneezing and now it has hit me like maybe I should be more worried than brush it off as sinuses?

He has no other symptoms. Congestion, cough, and sneezing. He does wheeze when he breathes but he has breathed like that since birth.

Should I be concerned? I’m trying not to freak out in the two hours I have to wait to call them. I also hate showing up at the doctors for something silly because I’m a FTM
