Its hard to know if he was really forced, Junior is probably so used to being filmed he doesn't understand the difference between off camera and on. He could well have just naturally asked him.
What I do find a bit worrying is that he thought Pete was having a baby. I am not sure the level of biological knowledge kids his age are supposed to have, but this is a bit strange
I don't believe Junior was "forced" into the conversation ..I'm referring to Peter .. The press story says Peter was "forced" into discussion with Junior..none of my kids have ever forced me into discussing a topic I'm not comfortable with. I can only speak about my own child and she knew women have babies from a young age because family members are having babies all around her..
