Problems with biological mom and inconsistent house rules

A stepmom asked recently:
I was just recently married, but been with the same man for 6 years now. We both have sons and I have known his son his whole life. His real mother has been in and out of his life, and she comes around when it is convenient for her. Every time she does show up, I have to let him see her, although I think that its just going to make more problems for him in the long run. My biggest problem is that he has structure here and rules. Every time he visits with his mother its completely different, she doesn't make him listen- she lets him walk all over her and she gives him everything he wants- no rules, no structure. He comes home thinking that it should be that way here as well, sometimes goes as far to say that he loves her more and wants to be with her. It really disrupts our blended family.

We won custody of him a long time ago due to her bad decisions to take him in bars and leave him downstairs to watch movies while she goes upstairs with men. I just don't know what to do, I have no patience for her and her stupid decisions anymore, and it's causing problems for him and my husband and me as well. I find myself being so angry and frustrated at my stepson, and his mom and everyone all the time now. what can I do??

Shirley Cress Dudley responds:
I know it's frustrating for you, but you're truly doing the right things. Providing guidelines and boundaries for your stepson show that you love him.

Since you and your husband won custody of your stepson, I would recommend setting up some visitation guidelines, or a formal visitation agreement with his biological mom. That way- she can't just come and go as she pleases.

I know your stepson is testing you when he returns from her visits, pushing the boundaries and seeing if you'll let him get away with anything. That's O.K.- maintain your houserules, and remind him that when he returns from a visit with his mom, your houserules have not changed, and your expectations of him have not changed. He will protest, but kids really do appreciate boundaries and know that you love them when you give them rules and guidelines.

Keep up the good work as a stepmom, and just be consistent, and try not to worry!
