I think that's good advice. I've seen some families where it just doesn't work. The step-parent might take out some frustration on the step-child, for example. If there is communication between the adults I think it can work, but it requires a lot of hard work.I think that has some merit to it, but every situation is different. I think the most important thing is for the biological parent and step-parent agree on discipline, or at least never discuss any differences in front of the kids, and that the biological parent back the stepparent up if they do discipline the kids.
