I think J$ was an attempt to increase views and that is it, plain and simple. They were both getting older and less relevant, the competition is young and timely. They are both money hungry and want to try and stay on top of the YouTube fame. Gin was on birth control, stopped taking it and boom pregnant. They knew their stans were dumb enough to believe it was a "miracle" and he has been their constant scapegoat for any and everything. They saw, and still see, J$ as a business opportunity. Now they see how the stans eat up anything regarding J$ and coincidently another "miracle" came along (oh, and now they have to work on actively stopping the "miracles"). They parade J$ around like an animal in a circus, constantly risk his safety and have pawned him off on at least 5 different caretakers (Sparkly Nicole, Disney Double Dose, English friends, girl who was at Ratatouille opening and now Lyn) and he is not even 3 yet. J$ is an afterthought and they constantly prove they could care less about him, just look at his 2nd birthday, he got to do what he does everyday - perform for the camera - he wouldn't have even had a cake had the neighbors not brought one over. Truly very sad, he will be consulting with Janette McCurdy in a few years to write a book about his dysfunctional childhood.
She said during the planned parenthood live that she was on birth control.
