I think immature would have been a better word. Some of her text messages and her general behaviour seemed quite teenage like. The rose petals and the notes. There was something else in the article as well but I can't remember what it was. It all just gave me the impression that the way she viewed the relationship was a bit of a romantic fantasy rather than the (grim) reality that she was an adult, in a position of power, sleeping with a teenager. I'm not sure I've explained it very well, it's quite difficult to put it into words.
She also doesn't seem to be able to think about consequences. She's clearly manipulative but some of it is very transparent, like the baby bonnet. I can only assume that she thinks it shows dedication to her child but she doesn't seem to have considered how it might actually come across to other people.
I wasn't suggesting I think there's any mitigation, I was wondering what she will present as mitigation (if anything).
As I said though, from the evidence presented so far, she has the potential to pose a danger in the future and it's not like it was a one off incident that she could claim was a mistake (still not acceptable). There were two different boys! One she sought out when she was already in trouble for the first. I don't see, at the moment, any grounds for her to avoid a prison sentence. Especially when you compare it to similar cases, for example Jeremy Frost.
