Wheezing...could it be Asthma?

My DD is 5 1/2 months and for the last two weeks has been making these wheezing sounds every so often when she inhales (like she is having trouble catching her breath).  I asked her Ped about Asthma and he said that her lungs are clear.  It just doesn't sound right to me.  
She was born nearly 4 weeks early and I was thinking that maybe her lungs were not fully developed and she may be having some sort of issue now....I know, it may be a far stretch, but I can't help but think that something is wrong...worse case that I was thinking was Cystic Fibrosis...am I just being an overly worried first time mother?

My dd is doing the same thing only she does it when she gets a diaper rash, so I think her wheezing is do to it hurting when I have to clean her up. But I still wonder if it something else so I will see if anyone else has any good info on this topic. Good luck

Hi.  I'm not a mommy yet but, I am an asthmatic and I know that they wont diagnose your baby until he/she is at least 2 years old.
I would be worried to if I were you.  Maybe it's a stuffy nose?

if she's wheezing, ask the doc about trying a nebulizer. if it helps, you'll have your answer.. or at least more information.

my dd has experienced wheezing too, both times it got bad she had bronchitis,

My dd was diagnosed with asthma at 12 months of age.  My mother saw signs of it from the time she was just a few months old.  I, being a first time mummy didn't realize what was going on until she got quite ill.

Lots of babies get congestion, but I would definitely discuss it with your doc.

Doctor has to listen while the wheezing is actually taking place--if it's asthma it comes and goes and when they're not having an attack, there is nothing to hear.
