are you qualified?

How do I even begin to prepare myself for this interview? Interviewing someone to do my job...to be the caretaker of my son...
How can I possibly have the right questions? My eyes are swollen from the very idea of someone staying here playing with him, when I should be; laying him down for a nap, when I should; fixing his lunch while putting in that extra cookie...but I can't. I am not angry, don't get me wrong, and I am not in any way upset at whoever she might be, it just saddens my heart. I feel just so very sad.
My prayers don't seem to be echoing the right words, I can't seem to form the right petitions for the woman that is to help shape the life of my children. Praise God that the Holy Spirit is stronger than I am right now...that His words are more eloquate.
I sit with pen in hand desperately trying to write some questions for her...but how do I prepare for this? How do I know what to say? How do I know if she is right? Will they like her? Will she love them? Will they all get along...will she be patient?
Oh, Lord, please guide the right person to my children!!! Please, Lord, Please! help me make the right decision...help me...
