Your assumptions are just not true. I care about my kids more than anyone else, and I want them to well. If they're struggling with something, I get them help because I want them to be OK. I do give them tests at home, and I don't tell them the answers ahead of time or grade them more easily than I would someone else. In fact, I'm teaching a high school class at our co-op, and my DD complains that I grade her harder than the other students

.
And, if one of my children struggles in spelling or has a learning disasbility, I would be the first to recognize it because I'm with him or her every day. I see how their minds work and what types of problems they may struggle to solve. I am the first to "admit" if my child has a problem, because I more than anyone, want them to succeed in life.
