S.H.
Take her to Urgent Care or the ER.
Again, since it is not getting better.

I have Asthma, since childhood.
It is serious.
Wheezing and not being able to breathe, at all, can come on suddenly.
And you cannot predict, that.
Get her seen again, by a Doc, because, the meds are not working.
You also want to make sure, it is not Pneumonia or anything or Bronchitis etc. And yes, these things can all occur, at the same time, along with Asthma.
And the baby is very, young.
The "steroids" and inhalers, are to reduce the constriction of the airways. ie: the inflammation of it. When the airways are constricted, wheezing and/or difficulty in breathing can occur.
Since you said, that she "sounds" worse, have her seen by a Doctor again. At Urgent Care or the ER.
