200ma is 2 tenths of an amp, not 1 tenth, and a car with this draw and a typical 125RC starting battery, parked when fully charged, will be down to 10.5 volts in about 10 days. At that point it is considered fully discharged and may not start the car.
Automakers strive for the standby current (called IOD or ignition off draw) to be 50 ma or less.
This allows about a month of standby time.
A draw of 6 ma or less is well within this spec, and is so low as to call the accuracy of the measurements into question. If it really is 6 ma this is not the source of the grand daughters no-start problem.
One possible diagnostic test is to remove the battery cable overnight. The next day, re-install the cable and again try to start the car. If it starts, the car has excessive standby loss. If it does not start, the battery is bad (perhaps with an internal short that doesn't show up on a simple load test).

In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
