That old brain/new brain struggle haunts every DBer to the max. It is funny because we don't even know that the old brain is working until whamo! It does take a long time for the new behaviors to work their way into the old brain and the others to leave. Each new behavior is transmitted, pondered by the appropriate brain section and then filed in the appropriate place. Bad thing is the time for things to get filed in the old. The same behavior has to be repeated over and over again until the brain buys that it is genuine.
I guess this leads to consistent changed behavior over time = trust re-established. Trust that feelings won't be destoyed again. Trust that WA's feel safe again.
Andy I think your plan of Sunday nights and Thursday nights is wonderful. I did it for awhile. Only 1.5 away at the time but I worked extra long each day and then split Thur night and returned Mon morning.
Now your looking at 6 months. Maybe you could even have some of the kids up during march break. Cool for them and big break for Mom.
