I am very happy to sign this. I had a neighbour whose first baby died from SIDS. After she had her second one she was given some sort of monitor to wear all the time I'm not sure how it worked and it was a help but was not 100% re-assuring. Fortunately the second one is now a strapping teenager but I think the anxiety was constantly with my neighbour in the early years . A test like this would have helped I think.
