My 4 yr old daughter just started the albuterol as well, it seemed to work good and the cough went away for like 4 days, then it came back. They put her on a liquid steriod for a week to get rid of the inflammtion in the chest, and a steriod spray, nasonex, for the inflammation in her nose. And they also put her on a little kid inhaler. Of course we have the cold mist humidifier in her room every night. I am only suppose to use the albuterol when she is bad coughing, and I havent had to use it in 5 days, which I am so excited about. I am using the little kid inhaler once in morning and once at night, and the humidifier, and her daily dose of singular. All this came allergy stuff came up last yr, and until 2 weeks ago with the possibility of asthma. But...like I said for 5 days and has been good. But...one mom who does the homeopathic a lot told me about vinegar and how it helps with coughing. So one night, about a week and a half ago she was coughing and it was driving me crazy so I said what the heck 1/2 teaspoon cant hurt her, so I had her take it and its nasty but I immediatly gave her juice, and I tell you what...she slept all night not a single cough again that night. The next night no coughing. Then the next night I did have to give her another 1/2 teaspoon, but again it immediately stopped the coughing. And that was last friday and so its almost been a week since then and I havent had to give her the apple cider vineager again but I would if I needed too. I figure its no worse than vinegar on a salad or sandwich. I am not sure if this will help with your kids being so much younger, but maybe can give you ideas or something. If nothing else talk to the dr about her heart racing after the treatments.
