Under no circumstance should any child be left with any dog of any size unaccompanied - period. Doesn't make a difference on the breed. I've seen more small-dog bites then large dog bites. But it doesn't matter, you should never leave them alone with any dog, or to play on the floor with one. It always amazes me how when company comes to my house, the first thing they want to do is bend down and stick their face in the face of my OEM!!!!

. I don't understand how people think it's OK to bend down and try to immediately make friends with a dog. There is a proper way to approach, and a proper way to pet a strange dog.
OEMs are bred to be protecters, and she is. I don't allow anyone near her without me present with the exception of my parents - she's a bitch and that's fine with me, she's an only dog and I have no children. No child is allowed around Belle ever, adults are given strict instructions on how to properly behave around her
before they meet her. Pitbulls have gotten a rotten name unfortunately, and they are some of the sweetest dogs I've known. Ones who have been fought and been through extensive testing such as the Vick's dogs can have a place in a home which meet all their needs. The dogs who have been bait dogs are more likey to be adopted however, but still must be carefully placed.
When I adopted Belle, she had to go to a home with no children (she grew up in a house full of 6!), no other dogs, no cats and no birds. She began showing aggression and the family became afraid, as they should be.
Bottom line is always be careful around any dog.
