If your other kids are able to handle S#2 and his problems long enough to baby-sit for a couple hours, then for heavens sake have them do it occasionally. Giving up their childhood!? How much giving up would they be doing if you and your W went out for a couple hours to ride the motorcycle, or go to dinner, etc? We're not talking about a 2-week vacation here.
And, let's face it, if it results in their parents being more relaxed and happier, they'll reap the benefits from that, too. You'll be leaving them a wonderful legacy if they see their parents affectionate and loving towards each other, HAPPY being together.
Honestly, you're a family unit. Let your kids help you. It will make your entire family stronger and more unified.
