I went through an ordeal where my 11-year-old daughter poisoned me by adding a mixture of Lysol and ammonia to my jug of Crystal Light. Yes, I got a few big ol' chugs down the hatch before I realized something was wrong.
Before the courts would finally grant me full custody of her at age 7, she was subjected to some extremely damaging situations while living with her mother and that side of the family. I knew the likelihood of dealing with psychological and emotional issues was all but a given, but the possibility of being poisoned was something that never crossed my mind.
The decision wasn't an easy one (although many on the outside assume it's a no-brainer), but I had her arrested. She (we) went through the process of being locked up, going to court, being placed on supervised probation, therapy, etc. It was a long, heart-wrenching experience for both of us, but I felt it had to be done.
We still had our ups and downs for a while, but it all paid off in the end. I still deal with some of the somewhat typical teenage stuff, but we are now closer than we've ever been. It's a constant work in progress, but I'd like to think she will grow up to be a wonderful woman and a productive member of society.
Dealing with a child who suffers with mental and emotional issues isn't easy, but much like other illnesses, the first step is the willingness to admit there IS a problem. Where your children are concerned, for countless reasons, that is often much easier said that done.
