DS is 13 and high functioning autism; DD is 7 and NT.
In a year or so I can well imagine being able to leave DD at home while I pop round the corner to post a letter etc; whereas at the moment I would be very reluctant to leave DS.
However, if DS had a friend of the same age with him, then I think I would feel confident to leave them, but am I putting too much responsibility onto someone elses DC?
And in a couple of years, could I reasonably leave DD (say when she's 10) to look after DS?
DS has a high IQ, very verbal (but in the semantic/pragmatic sense) and zero common sense, which can make him something of a loose cannon....
