Wheezing?

Update -- I called the pediatrician and was told to just keep an eye on him. She thinks it could be just from excitement and nothing serious, since he does it mostly when he's excited and doesn't seem to have any other symptoms.

So since yesterday my 10 month old has been randomly breathing in making a wheezing sound, usually when he's happy or excited about something. It doesn't look like he has trouble breathing but it sounds a little concerning to me. Should I be worried, or does it sound like just a weird little quirky thing he does when he's happy? He has other similar things that he does when he's happy too
