You've just described what I would consider to be totally appropriate and correct usage of the badge. I presume that if your son was with you and another passenger you wouldn't take advantage of your son's presence to park in a disabled space so that your non blue badge holding person was able to get to the shop easier.

I apologise for having used the term 'able-bodied' to describe someone not entitled to the use of the badge. I should have taken into account the people like your son who are also legitimately entitled to one. My complaint was about people who are not entitled to one taking advantage of a friend who has one and taking up a space which may have been needed by a genuine person.
