Just saw NBC had a story about this. It seems that children sleep deeper than adults. They are finding the kids are sleeping through the alarms. People are trying to work out a new alarm system that WILL wake the children. I think they should just make it the Ice Cream Man song. Ding ding ding.
So, if you guys have children or have family with kids, bring this to their attention.
