This could be almost anything, from an underdeveloped nervous system to night terrors or distress from being moved from one home to another.
It would probably be very helpful if you scheduled a consult with her pediatrician. Being born one month premature (at 36 weeks gestation) isn't usually a big cause for concern, if everything else is fine. I don't know what kidney disease she has, but you are entitled to more information about that, and how that may be affecting her.
Did she have a guardian at litem, or a CASA volunteer during the legal custody process? They would be a good resource too for help.
In the meantime, don't leave the TV on all night. While that may seem to be a soother for her, it's not a good thing to have constant audio stimulus throughout the night.
The disease causes her to have only 10 percent use of one of her kidneys and if something as small as getting a uti more than once can cause her other kidney to fail. And she was with the mother up until we were awarded the joint custody. The mother has told us many times that she has had her sleep in bed with her since she was a newborn bc she fussed the first night she had her in a bassinet, also that she always holds her, carries her everywhere no matter what. So now if we try to put her down to play she freaks out and wants to constantly be held or right next to us. Also she wakes in the night and freaks out if she doesn't hear or see her tv on.. idk what to do that can help her adjust when her mother condones the behavior. She even admitted she thinks it is funny when she trues to hit or kick so she allows her to do it.
So this is a child who is a very serious health concern, and probably won't grow at a normal rate, and needs constant monitoring for possible serious infections?
The way her mother is treating her is pretty normal - in my opinion - for mothers of seriously ill children.
In the meantime, I would suggest again that you have a consult with her pediatrician(s) for guidance with how to make her transitions to your home easier.
Her mother is suffering, probably, with fear that her daughter will not live through childhood - which sounds like it's a real possibility.
Her mother actually says she is perfectly healthy and is denial of the fact that any little thing could change her status of health.
Dad should speak up and get her looked at. He has equal rights he can take her. Waiting is only a discount advantage to the baby.
He has tried, she takes into court to try and take her from him. When he called the doctor to see if she had night terrors she told the courts she wants his time with his daughter taken bc she is in harm with him. She lies and fabricates everything to make him look bad so that he no longer gets his daughter..
