It is a spin off of Toddlers and Tiaras. She was such a train wreck they thought she should get her own show. Frankly I find most of the reality shows to be the 21st century equivalent of exploiting people as the side show "freaks" of 100 years ago.
the reason why such reality shows gain popularity is because when people watch them it makes them feel better about them selves. we don't realize it but when you think about it when you watch jersey shore the whole time your just making fun of them. before reality t.v there were freak shows, like seriously people took the time out of their day to go out and see deformed people for fun.
I feel so sorry for these people. It is appalling to me that people watch this show, it has to be just to ridicule the actors. That mother is committing child abuse to hold her child up to ridicule, and teach her how to be so obnoxious. How in the world will she ever have a normal life?
