It's vital to have a plan so here are practical do's and don'ts for stepparents. Do strive for unity in your parenting with the biological parent. Discuss your values, expectations, the boundaries you want to set, and the consequences you'll implement if the rules are broken. Don't be harsh or punish in a way that the biological parent wouldn't. And, do deepen your relationship with the children no matter their age. Relationship adds to your leadership and influence in the family.
