You don't want someone who can't tell the difference between having a different opinion and dismissing your opinion.
I'm sure there are people who can toggle quickly from all-in caregiving to structured socializing, but I can't think of any offhand.
No matter what else comes, your courage will be your companion for life.
Make sure you have legal cover for what you're doing.
Once given, a gift is yours to use, store or dispose of as you see fit.
I have no quarrel with people who lack the skill or temperament to care for small children.
