Food and water taste different, and things smell different. The sense of touch is different and the person whom they have come to love and trust is gone. The child has little control over the situation in which he finds himself. They cry, grieve, and manipulate their environment in any way they can. They can bring adoptive parents to the point of exhaustion and can upset an entire household for months.
Parents begin to question their parenting ability.
Along with those doubts, quiet anger bubbles up to cause frustration. They need to see their child much like they might see any other person who came as a guest and ended up staying. Real parents love real children in a realistic length of time. Fantastically unrealistic parents bond to fantasy children immediately. Somewhere between success and failure, liking and disliking, acceptance and rejection, your child lives.
