T.,
Schinnen is a nice little community. Schinnen the base is basically just a PX, Commissary, Fitness Center, Post office and Bowling Alley and a few military offices it has only a handful of active duty members most all MP's. It is just basically a support bases for the 2 NATO bases that are 10 minutes and 15 minutes away for all the American personal and some Canadian personal.
As for your daughter she would go to the international school where the rest of the American kids go from the NATO bases. They do have a preschool at the school if your daughter turns 4 before 1st of Sept.
As for working full-time, short of working at AAFES or the CDC there is not many options or if you are in the GS system. Also day care is a HUGE issue for the bases here especially for your daughter's age. I know of a singe active duty mom that has been waiting 6+ months to get in! They have in the long range plan for a big CDC but that is 3 years down the road.
We are stationed at the JFC Brunnsum NATO base but it is all the same as you would have at Schinnen.
