Apologies for not responding to your comments yesterday. I was maintaining internet silence because of the SOPA/PIPA protest. (

Dustytoes - I'm glad that I had that CM detector too! There are a whole host of things which could make your son's life easier. Unfortunately most of them cost too much. At least in Britain, this one is free. I'd be grateful if you'd report back on whether this is also true in the USA.
Lorren - I'm glad that there are alarms for the likes of me too! ;) Thank you for reading and I'm pleased that you enjoyed my article.
