As an adoptive parent, you go into adoption loving your children and feeling that you are going to give them the best life possible, but also determined to do whatever is necessary to help these kids grow up to be properly educated and self sufficient. With a fetal alcohol child, those ideals quickly blow up in your face. They have behavioral problems that seem minor through grade school, many are diagnosed with ADD or ADHD. They're disorganized, have difficulty with dates and time, and sometimes get suspended from the bus for fighting or being disruptive. Then, their grades begin to slide in Jr. high and keep going downhill in High School. They typically just stop doing their schoolwork and fail most if not all their classes, at that point, they are only interested in socializing in HS, not academics. Many drop out of high school. If they are not "allowed" to drop out, they will run away from home.
They are defiant to an extreme where if they are told they cannot go somewhere or do something they want, they will sneak out. I know "normal" kids may sometimes do this, but the difference is, a fetal alcohol teen can get caught after sneaking out and not be the least bit remorseful for what they did, but angry at the parent for giving them consequences. If grounded for their behavior, they will sneak out while they are grounded. They live like they have nothing to lose and are angry at anyone who tries to stop them. Most "normal" teens have some direction and a means to get to a future they have chosen for themselves, while fetal alcohol teens don't plan, can't seem to get organized, and appear to have no motivation, they just let things happen. They are usually compulsive liars, they will fantasize, and relay it to you as though it was the God's honest truth, frighteningly they tend to believe their own lies.
They are prone to fits of rage and can be a physical threat to those closest to them. Fetal Alcohol victims find it difficult if not impossible to control their impulses, for that reason, they can get into trouble for improper sexual conduct, theft, compulsive lying (for no reason), and as you can imagine, other problems that would crop up without any impulse control. Many Fetal Alcohol Effected babies end up in the prison system in their adult lives.
