Ds has been wheezing when inhaling off and on for part of today. He is not sick ,and is acting fine. I called the doctor, and she said if it was croup, it would probably come on pretty quick, and told me what to do, but she said she would be surprised because he was not sick prior. I think it could be a new thing he has learned ( he's 9 months) and just likes to do it. It's at random times, but it does happen when he's been crawling alot too. I also asked the doc about asthma (sp?) but she said he would be wheezing on the exhale as well, and it would be pretty bad. Any thoughts?
