Hi J. - I'm glad that your son got the care he needed and that he's feeling a little better. He probably has this awful bug that hit my son and a lot of others I know here in Parker. If it is, you'll probably be dealing with this for at least another week.
The steroids taste awful and with my son, the first dose barely any made it down. I crushed it and mixed with some OJ in a syringe and somehow it masked the taste. Just a thought. The first couple of days are the worst with croup. My son responded best to a cool mist humidifier in his room at night.
I learned that croup is laryngitis in kids. The croupy cough comes from the swelling of the larynx which is why they give the steroid. This will probably turn into an awful cold so be forewarned. Ear infections after croup are pretty common, so if he spikes a fever over 100.5, call your doc.
It took a good 10 days for my son to start feeling better. He was incredibly tired. He would try to play, last about 10 minutes and then go lay down. He is just now getting his appetite back. He still has a horrible cough. The doc said it could last 3-4 weeks. If you think your son is wheezing or is having trouble breathing, be sure to call your doc before administering a neb. If it's that bad, then he may need to see the doc right away.
I hope he feels better soon!
