We have been married FOUR years.
My oldest SD is special needs with an IQ of 70. I THOUGHT I knew the discipline style of my Husband, I THOUGHT he was consistent, firm but kind, etc...but it turns out that is only to his "normal" child, my bio-children, etc. This "special needs" daughter gets away with so many things, less chores, he does her homework, believes her lies, is inconsistent with consequences, etc.
