Kristin, I'll be honest with you. I haven't read all of your replies or this entire thread. The first thing that stuck out is that your family didn't want you to pursue a criminal charge against your uncle and you have made peace with him for the family's sake.
Get the hell away from your family, they are sick people and worthless excuses for parent. I will tell you if someone did that to my child, I would be typing replies from prison. The fact that they are more concerned about what problems it would bring to the family discusses me.
Do you let your child go to your parents house unattended? Do you let your child around your Uncle? I won't go any farther, but you seem intelligent enough to see what I'm getting at.
IMHO, you need to seek some counseling, move far away and cut all contact with your family, and focus on making a better life for you and your child. Nothing you have posted would DQ you, but your decision making processes as an adult will tell if you are emotionally sound enough to do the job.
Excuse me Officer, I have a stupid Question. "No problem, I've got a stupid answer for you!"
