Is it worth a trip to the dr

I have a 6 month baby and for the past couple days he’s been coughing and I don’t know why. He doesn’t have any kind of fever and he hasn’t been acting different. Normal teething stuff here and there and he’s generally happy.

He has found his voice and has been screaming-not mad just being loud. My husband says this is why he has been coughing.

I feel like I’m quick to react and call the dr for everything 🤦🏼‍♀️

We do have the humidifier going by his crib.

Anything else we can do?
