As I'm reading this I'm right there with you, it is truly infuriating the way they do everything they can do to make you feel powerless, and terrifying that they have the ability to steal a child from someone simply because they decide to.
I have a friend in Florida who also went through a horrible ordeal. She and her husband have five girls- I can't tell you how many people judge them for that alone, for having 'too many children'. They really wanted a boy, so instead of stopping at the three children they initially intended to have, they tried twice more, that's all there is to that, it wasn't 'irresponsibility' on their part as has been claimed.
Anyway, having five children does take a bit of finance which means they were both working full time when the kids were young (I'll mention here that they did not use any services from the government such as welfare). They had found what had seemed to be the perfect babysitter living right next door and all was going well...until they found out that the babysitter's boyfriend had touched there two older daughters, twelve and thirteen at the time, and naturally called the authorities.
Instead of being treated as the victims in the situation they were immediately treated as if they were at fault. They didn't understand their rights at the time and were intimidated into letting the DCF into their home-- which was a bit messy considering their work schedule and five children. And that was all it took, a messy house, and suddenly they were in a nightmare.
Fortunately their parents lived in the area and were able to take custody of the children as the battle ensued, on that took six months to resolve. This is obviously making a long story short, but needless to say, they still have nightmares at what might have happened if not for having supportive family.

I'm sorry that happened to you, it truly is a corrupt system we have.
