It might be exactly what she wants.
I suspect this as well. And because she is hanging on to quite interesting beliefs, I think the way I've heard Rikers is - might give her in some absurd way.... Solace.
My random thought on her behaviour, as something more is coming out now.
- What is the age, she think she is?
Her way of naming the boy as Jacob, which is masculine version of her own name. While this necessarily do not make you question of this, because it do happen with more adult parent(s) as well.... but little girls in some studies have found to name their dolls by close name to their own, version of a nickname quite often.
Another point to this is that the boy is non-verbal and allegedly autistic. Could it be, that she might have neglected this phase of his life? As she didn't actually speak to him and occasionally children need encouragement to learn to speak as well as learn new skills. Like he wasn't real child to her?
Thirdly, that she has been allegedly said to have been pushing him around on strollers. True, it could be, that this little angel boy had more issues that we knew (or anyone else.). But even then, he would had been provided the right size of wheelchair or in some cases, actual strollers. Otherwise it could be once again, some version of doll play.
Fourth, her saying that she can't have children (and apparently doesn't have had periods.). Now this breaks this up a bit, since to know of female body functions, you have had to have someone tell about these or actually had them. And some know at fairly early on about these.
However... I wonder could it be, that since she doesn't have them now (she is on that stage of womanhood after all), that she feels her right to say this. Also depends who questioned her (and the situation.), not to mention - it's pretty private matter, that is going on in our bodies. Not all like to think or talk about them.
Also she knows of Jesus. Granted, most of church goers know of him. and if the religion plays bigger role to her or to her family as she was little. Relating to the body functions earlier... we know that some parishes and churches within them, can be more strict about these than some others. So, it could be factor for her saying these. And on the subject, allegedly claiming to be a Jesus Christ. Some teach this, or she could had come to this conclusion on her own. All of this speculations if course.
Naturally. she could be as well just incredibly disturbed person.
Naturally these days, you don't necessarily need to have the two people tango part, because fertility clinics exists and some just decide to have child with a donor. Nothing bad there eithet, but I find it rather unlikely on her case.
We also have the possibility of her being a victim in some way, we know it do happen. So trauma of such event, could alter her mind and she tries rather to settle on more comfortable age in her mind.
We already know, that she really has issues with strange people her. and her flipping out reminds me of seeing some kids literally going all ballistic in case of stranger danger. Kids are often taught to trust police, and not let strange people in.
Her way of acting of not wanting to speak on court, but obviously she has talked with those representing her, shows this weird stranger danger. Or it could be case of stage fright. It would be better in my eyes, if it would be told, why she won't speak on behalf. She is currently playing the hide behind someone's back.
Also her being tight lipped of where is this little boy, sounds like "It's a secret, I can't tell you." Which is really what we can expect from our daughters. Which is pretty frustrating.
But ultimately, this case is super sad and makes us tear inside, that this little boy was taken too soon.
