My child is now 6 years old and we adopted him when he was 4. Initially he was very quiet and subdued but we passed it off as him warming up to change at such a tender age. As he has been growing up, he's gotten much more angry and moody than normal and my wife has a very hard time dealing with him. We've given him our time, attention, toys, everything. It pains me that we cannot get him to happily accept our home.
