As a parent of such a child - yes and no.  The monitor consisted of a
base with some firm(ish) vinyl tubing on its underside.  There was a
microphone on one end of the tube and the other end was sealed.
Compression of the air in the tube due to breathing was detected.  Very
simple, and effective.  There are newer detectors which incorporate
other detection strategies (doppler, for example) but the one we used
was very reliable and simple... [and had no PIC in it :-)  or any other
processor :-)]
