In AA it's said that anything you put ahead of your recovery you'll eventually lose. I keep that though going when it comes to my recovery, it has to be top shelf, top of my list.
In al-anon if a new comber shows up with a child, one of us will babysit in another room so that the person can attend the meeting. some groups even offer babysitting and it's free!! Some members have babysitting age children and arrangements can be made. Find a meeting bring your son and see what may be available.
