A learning disabled, ADD, or ADHD child usually needs a distraction free environment and multiple sittings to accomplish all of the work. Sometimes working parents insist that homework is done at their convenience. For elementary aged children and some middle schoolers, that sometimes sets the stage for confrontation. Working out homework time as a family often works well.
