Its like dating, again

My work hours at the hospice facility are kind of challenging. I knew that going into the job.  What complicates things is that on the days I work, I have to be at the office by 4:30 in the afternoon. Now, with MG here, that's do-able. The beginning of the shift is the busiest, I'm usually doing stuff until around 6 pm, then, I come home and field phone calls, and go out if I am needed until 8 am the next day. MM gets home between 5:30, and 6.
And so, the conundrum
when MG does leave, who is going to be home to manage the small child?
I don't know any local kids that I would want to come. The lady/friend who was watching him while I oriented to my job has since moved away. My family is not close enough.
So, I did what every one does these days.
I went online.
Specifically, "care.com"
and to my surprise, I have 2, very viable people contacting me, to watch him 2-3 times a week from 3-6 pm, in our home
One is a single mother, EMT qualified, who has a boy 1 month older than MB. This is great, because he'd have a friend to play with, and she gets little boys. She has to, right, her boy is still alive and walking... My slight hitch is this. What happens when her boy gets sick? I know, I know. MB is going to get sick eventually, too. But still.
The other lady is a grandma type who watches her grandbabies. Also boys. But she wouldn't be bringing them here, they are much older than MB. This appeals to me, too. Her kids are raised and successful, and she obviously likes kids.
I'm meeting them both this week. Not at my house, not yet. To get a feel for them. Because I am already kind of torn.
Its totally like going on a date. Kind of. Sort of.
I hope one of them is a toad so it makes my choice easier.....
