Family gets your best or no one gets the rest is most assuredly GBD
I developed the discipline style and I came up with the principle
But let's make sure you're using it correctly--and I assure you that it leaves PLENTY of room for just being at home. Hanging out lounging and watching tv with your family in your sweats fits perfectly fine with "your best" if you are TREATING everyone with respect. "Your best" isn't about pretending or putting on a show or using the fancy china you only save for visits from the queen
What it does mean is that you don't get to treat your family like garbage and then go to sleepovers and play dates and treat the rest of the world like royalty
Plus, ime, if my children can't keep themselves together without falling apart then they are getting sick or overtired or otherwise not able to be successful at other events either.

One thing that I find myself wondering when I read the OP is if ds is an introvert and if the current schedule might really be overwhelming him. Plus, that level of physical activity is exhausting. Is he getting enough rest and eating enough to sustain this level of physical exertion?
