Let us say your husband is Eric.
I think you have to
- say “no” means “no” and mean it. (Variation: “Hi, Mom. Oh, yes, Eric’s mom called, and she thinks we ought to change our minds about having you come to stay with us. You are going to love her. We’re not changing our minds. We have had everyone and their dog Mike call us, we’ve thought about it carefully, and we are sticking with the original plan. Sorry, but the discussion is closed.”)
- and then tack on: “…and if you show up anyway even though we asked you not to, we are going to get you a hotel room and you are going to stay there. I’m the parent this time, Eric (or whatever your husband’s name is) is the parent this time, and our number one rule for your grandchild is that we make the rules. No exceptions, you may as well realize now that we mean what we say and say only what we mean, and do not say we didn’t ever tell you that.”
- decide on natural consequences that will follow for people who intentionally violate your boundaries, ranging from “warning issued because maybe you didn’t quite understand” consequences, through “ten yard penalty and loss of down” consequences and all the way up to “ejected from the game” boundaries. (Let us hope no one gets themselves banned for life from the Hall of Fame.)
- then select the four people you are going to get pre-approval from as your guilt trip survival support group, so you won’t wear out one person with your venting.
- When the push back comes (and some day it almost surely will):
a) enforce the boundary as you said you would
b) repeat “the definition of a dysfunctional family is any family with more than one person in it. We may not be normal, but we are definitely typical. We’ll get through this.”
c) try to laugh
d) if laughing doesn’t work, call your Vent Support Network.
If you draw your line and defend it, you may get 20 years of snarky remarks, but you will get through it and this will pass. No, there is not an easier way, because the other way is to just parent exactly the way your parents tell you. (Tell me if that doesn’t curl your hair!

)
You already know children test boundaries. Well, just think about it: Everyone does. Grown-ups test boundaries, too. When you went from child to adult, your parents may have even tested your adult boundaries. Even if they didn’t, the push-back you’re getting now seems to suggest they are going to test your boundaries as a parents dealing with your child’s grandparents. (Note the plural: parent
s dealing.)
When you become the adult and make rules for your parents and in-laws that are more restrictive than they like, you should plan on having your boundaries tested. As with children, you should have a natural consequence ready, and then another consequence (at least) in reserve to add on for continued refusal to comply.
You are one of the smartest people on this forum. You know all of this. Actually doing it, though? Don’t skip step 4. You may want more than 4 people, even…)
