I should mention, too, that I didn't hire boys to babysit my kids. Not because I wouldn't have, but I didn't know any. I suppose I could have done a better job seeking them out, but we really didn't hire many babysitters when my older kids were little. My kids are now 7, 13, 16, and 19. When my youngest was 1yo, my oldest was old enough in Maryland to babysit (13yo) and mature enough for short periods of time, so I didn't need to usually hire anyone for him. And now I have Jake's older brothers to babysit him.
Also, I wanted to add that my teenage boys babysit boys and girls. I am so glad that the parents don't have any problems hiring boys to babysit. They know my boys (neighbors) and it's usually for one family, but my 16yo is usually the one they call and there are girls in the neighborhood that they could call.
