Sow a thin cloth lining onto the inside surface of a normal reusable
cotton diaper with thin wires running parallel just under the surface, so
as not to bother the baby.
The idea is, that when baby has soiled said diaper, electrical
conductivity between the wires is (hopefully) made. A small
button on the front of the diaper, will house a tiny LED and button cell
battery. The electronics are housed in a snap-on button so it can be
removed and placed on the next (clean) diaper.
So next time baby has made a mess, you can know it's time to change!
