DS was described recently as a happy wheezer because he was doing the classic wheeze, but was happily carrying on playing etc. He wasn't distressed or clingy or anything with it. He is 3 though, so a bit different to a young bub I would think.

We were at the hospital with him, coz he did get very lethargic & his breathing was really laboured, and they treated it as an asthmatic attack, but because he had a fever as well, the GP was reluctant to say it was asthma, rather just that he's prone to wheezing if he has a chest infection or something, so she reckons he had bronchiolitis. But it was at the GP's the next day that she described him as a happy wheezer. We haven't had anything since, so I'm hoping he doesn't show signs of asthma as he gets older.. my BIL had childhood asthma.

Definitely have a chat with your doc about what to look for. I knew nothing about what wheezing looks like (I've heard it before tho) so just knowing physical things to look for helped me feel more easy.
