Since you supposely have knowledge about MMA Fighter & Wrestling, you need to write about that and leave the children out of it because you know nothing about what you're talking about when it comes to the children. I know that you say your story is made up, but if you are so concerned about things being accurrate, you don't have any foundation to build on because you have no knowledge about how the laws work and what is required when doing basic things with children. I can't imagine anyone could be so naive on the subject of abandoned children that they would think that they could get away with the things that you have mentioned here, but apparently, you are.
