Well my son is 2. He also had no problems when he was born up until now. Late December maybe about a week or so before Christmas my son got a little cold. Semi wheezing but I didnt think anything of it so I didnt take him to the docs. But maybe 2 weeks later, the first week of January, he got sick again. Wheezing, very lethargic.. This time it was bronhitis. They gave me Zithromax. Also a steriod to open his lungs and clear the imflammation. Exactly a month later, and im not lying.. exactly.. maybe 2 days off but to date.. I then took him to the ER again because he was wheezing, chest caving, also vomiting.. lethargic. Didnt want to do anything. We were in hawaii, visiting my family.. So the ER said he has asthma. Gave him the steriod again, sent me home with more steriods and a nebulizer and albuterol.. Now again, exactly another month, here we are again.. ER again, wheezing, vomiting.. Now I think its from traveling and we wont be traveling for awhile anymore but I need to know if this is common? I mean december january feb and march.. ? is this normal? has anyone elses kid done this or acted like this? Please help. One doc says its the traveling but the other one said no its not.. Please help..
