Veteran stepparents often give this advice–Round off your rough edges. If you’re a naturally angry, critical, quick-tempered, controlling, or stubborn person guess what? Don’t expect your stepchildren to warm up to you. Or your spouse to trust their kids with you either. I’m constantly amazed how some people think that just because they are an adult, they can treat a child poorly and still expect the child to like and honor them. No, round off your rough edges and be likeable.
