Reading your question has brought back many fearful nights with my son who  by the way is a strong, handsome 28 year old today.  He was in the hospital every fall with croup up until the age of 6 years.  Unfortunately, yes, he then became asthmatic. The specialist who took care of him and occasionly seems him today confirmed in his case one would be connected to the other.

My son has not let anything stand in his way to become an accomplished athelete - baseball, basketball and a tournament golfer.

Good luck to you.

My Grandson is now 15 years old.  He had 3 bouts of croup before age 6 and the doctor told us that having 2+ bouts before school age has been a sign of future asthma.  He did become asthmatic.  He played all kinds of sports - we gave him breathing treatments before the games and always carried an albuterol inhaler in case of an emergency.  He was diagnosed with "exercise-induced asthma".  That was in Houston where the heat is high as well as the humidity.  We have since moved to Colorado where the humidity is low and the heat not as intense.  He still plays sports, even soccer, and has had only two episodes that I (his Grandmother) know of.  My daughter (his Mother) claims that the move cured his asthma.  I do not think this although I think the heat and humidity in Houston triggered it more often.  He does not take the breathing treatments or use an inhaler in Colorado.  Asthma does not mean that a child is restricted from anything - there are amazing new treatments to subdue it.  I remember the doctor preferred not to call it "asthma" because of the stigma but rather to refer to it as "airways disease".  Good luck and your child never needs to be restricted or stigmatized from having asthma.
