Does anyone have any information regarding a blended family? I have a friend that is considering marriage and is concerned about her future husband having a good relationship with her children.

I agree that there will always be conflicts within a stepfamily.  I was part of one for 10 years, or maybe I've said that incorrectly.  I am a widow, but I still consider my stepdaughters (my late husband's children) and their husbands and kids my family, and they still consider my son and his family (and me) as family.  It may seem that all will be much easier once the marriage has taken place, but, as I was actually told by Joe Beam himself, before I married, it won't be.  We had a successful marriage but believe me, it took a lot of selflessness and sacrifice by all parties involved.   The 4 kids involved are now all grown and have children themselves - one is now a stepmother herself.  Perhaps I should send them this way and let you get the perspective from the children of "blended" families.

You can get more information on blended families at http://www.stepfamily.org.

As a former step mother..and when i say former i dont mean we divorced, i adopted my step kids, communication with the kids is key..give them some sort of feeling of some kind of control over their lives..ie asking them how they "feel" about certain topics, giving them some choices.
Not to say that they wont have any problems arise, but the stronger the foundation the easier it is to overcome any situation.
