When it comes to adults, I think this makes a good reason for training. Perhaps the best behavior hurts someone's feelings, or causes someone to feel judged. Foster children are often misunderstood and misunderstand others. In a moment of anger, we may feel the best behavior would be to tell the child how it was for you as a child, but perhaps the child feels judged, and that they can't measure up to you.
Training helps you know the best behavior for the situation. I often hear people accuse foster parents of "doing it for the money." Others accuse foster parents of taking children in for personal gain. I don't believe anyone starts out to harm a child, but without training and active support, sadly it can happen.
At Atkinson Family Services we seek foster parents who want training, supervision, team support and have the knowledge that they are fit for the job.
