Please remind me why we got this dog!

The picture of the first day we got her helps, but I woke up today and needed a little reminder as to why I got this puppy. I am a new mom and still have to get up every three hours to feed our boy. At 2 in the morning I woke up to a stinky mess in Africa's crate. Despite her relieving herself before we put her in her crate like we always do she decided to have an accident big time in the middle of the night. I have replaced 3 pacifiers, lots of new diapers, some baby clothes, a bottle, and who knows what else is yet to be noticed as missing. So I bring you a quick story why we thought she would be good to have with our kids.
We were sold on this breed when my husband heard that a Father and his son were in an outdoor shopping center with their boerboel and the story goes that the Father had to step inside of a store for a few minutes that did not allow dogs. A bystander observed the Father perhaps jokingly telling the dog to take care of his son even though the son was around 6 or 7 years old. The bystander then observed a mischevious fellow zoom in on the abandoned child and begin to approach him. As soon as the dog saw this he got up and layed on top of the child without taking his eyes off the suspect. This of course deterred the individual and he kept walking. The person who observed this occur went up to the Father when he returned, told him the story, and asked what breed the dog was so he could get a dog like this himself. We have also heard from another boerboel owner that their dog would walk around the edge of the pool when their children were playing by the pool as if to make sure they would not get near the edge or fall in. I guess even though Africa is driving me crazy destroying my son's things now, she may be helpful with him later.
