The precedent has been set with regards to children on the show. I saw all of 2 minutes footage of him with his daughter on the last show, in the park along with his parents. I don't see him dragging the poor child along with him on dates! Seriously, if they are going to bill the lead as a single father or mother, of course the kid is going to be a part of the show.
To me, that is very different than the train wreck that is the octomom. At least, a different level of exploitation, if you will.
