3. Leave Discipline (for the most part) to the Father.
These are not your children, and although they should respect you, discipline should be left to the children’s biological parents until the children trust you and are comfortable with you. Some men may say that you have the authority to spank or give their child a time out, especially if the child lives with you both. But take caution with that, because that can go left really quickly since most parents don’t do well with other people laying hands on their child. He may love and trust you, but the child’s mother may go off on ANY woman disciplining her child. Your job is to enforce the rules you all come up with, so a discussion on each person’s role is essential so that you don’t overstep your boundaries. The child should, however, ALWAYS respect you; and your man should be fair and consistent in regulating this so that you don’t feel like the evil stepmother.
