Ongoing wheezing

Anyone else have issues with your little one having ongoing wheezing? Have you tried anything that was helpful?

My son has wheezing but no other symptoms (other than colds here and there) and otherwise is pretty happy. The pediatrician didn’t seem concerned but still makes me nervous. Here are some of the things I’ve tried but so far have had no luck getting the wheezing to go away:

- humidifier in the room

- giving him some water in a baby bottle

- Vic’s baby vapor rub

- baby Zyrtec

- saline spray and bulb syringe/Frieda to clear the nose

Any suggestions would be appreciated!
