My heart goes out to you both with this problem Tonya.
We went through agonies when our daughter Elizabeth (now 26) was growing up with her asthma - she spent a HUGE part of her life in hospital - it was very tough for all of us.

A couple of things spring to mind:-

Is he maybe NOT taking his tablets because he feels 'different' when he has to take them? You know the 'I'm the only one having to take these - so I won't' syndrome.

Is he getting teased or bullied at school with regard to his asthma?

Does he see an Asthma Nurse - as opposed to the doctor? Elizabeth found this such a lifeline - lots of things can be talked over - sometime Mum isn't the answer - someone removed from the situation can be a great help.

Maybe he's bored with taking his tablets. A star chart can make a big difference. Every day he has to take his tablets in front of you or Daddy and when that's done - HE gets to stick a golden star sticker on a chart, calendar or whatever. It's better if this is at his height on the wall. When he gets 7 stars in a row - he gets a little present - a tiny toy car or something similar.

I hope these ideas might help you sort this problem out - good luck.
