1. Look carefully through the child's hair, and if you see the tatooo "666', RUN and don't look back. If not, get to know the child a bit.
2. Keep in mind is that 'other people's kids' are always more poorly behaved than you are sure yours would be.:p
3. Most children act their worst the first time they meet someone (uncontrolled excitement I guess), so don't be too put off my 'first' impressions.
4. I'm assuming widowed since there's no such thing as divorced Catholic, is there? Anyway, sometimes 'Dad' can complicate things in that the child tries to sabotage new relationships hoping Mom will go back to Dad. Better off if he's completely out of the picture.
5. The younger the child, the more adaptable (usually).
6. Mostly it depends on whether or not you LIKE kids.
Good luck!
PS Don't ever be left alone with the child and a full roll of duct tape
