OMG! My husband has much more patience in some areas with our son and can get the giggles out of him much better than me. It's maddening! I feel your pain! (I used to think I was an incredibly patient person until I got married and had a child. And *POOF* that patience went out the window.)
That being said, I've learned a lot about myself over the years (our son is 12) and have realized that I have certain expectations that get in the way of my relationship with our son. Does your husband just respond to the moment and get your son out of it? I tend to get all balled up in the big picture, responding angrily that he's not responding the way I want him to, and then I fear this will be a pattern that will affect him in his life as a whole, and I freak out, responding more harshly than the situation may warrant.
Does this sound familiar at all? If so, chill in those moments...and...take it one step at a time. (It's a small battle you're dealing with, not the entire war, right?) Stay in the moment, rather than seeing it as a larger failure that undermines your skills as a parent or teacher. And...if this doesn't sound familiar, just ignore me. : )
But seriously, I learned a lot by reading "Raising Your Spirited Child" by Mary Sheedy Kurcinka. Ironically, I realized I might be the spirited one in the relationship instead of my son. It was sometimes (not all the time) my response that fed the reaction.
However, there was also something else going on. My husband and I respond very differently to our son and to the world at large, and we have very different expectations with respect to behavior. I'll admit, I'm somewhat of a perfectionist that wreaks havoc on occasion. But I also expect a person to be respectful...even when they're angry.
Anger is one of many emotions we all have. It's healthy to express it at times. But when it becomes a habit, it can be destructive.
The problem was that my husband unconsciously, and sometimes consciously, was undermining my relationship with our son. And we all played right into it. Our son's behavior began to manifest itself as anger and I began to be the "mean parent" and my husband the "nice parent".
It took us years to work up to finally going to a family counselor last year. It was greatly helpful. I realized that half of my anger toward our son was actually anger toward my husband. I love my husband dearly, but he can be very flip and sarcastic at times. He also can dance around real issues with humor, rather than dealing with them head-on. And, truth be told, I can sometimes wimp out on what I think is best in a particular situation when they don't like what I'm saying. In the long-run, I was just getting more and more angry at them both and they played the "mom's being unreasonable" part with a flourish, abdicating their own responsibility for the situation as well.
Our son has come around to realizing that we, the parents, and he, the kid, can be jerks at times and we can also be good listeners and great support to each other at other times. It's a delicate balance that always needs work. Sometimes our kids are our best teachers for getting us all to look at things with a clear lens.
Years ago, I read a bunch of books by Harriet Goldhor Lerner. They're great and they're all part of a series I call the "Dance" books--The Dance of Anger, The Dance of Intimacy, The Dance of Connection, and yes... The Mother Dance. I find myself thinking it's time to read them again. They might be helpful for you, too.
I still think I get treated like dirt sometimes, yet it's a lot better than it used to be. I have to remember to hold myself responsible for my behavior and for them to hold up their sides of the bargain as well--to stop the overfunctioning tendency and the underfunctioning tendency. A friend of mine always used to say that whining is stuck crying. And our job is to figure out what the true issue is at hand.
So, I feel your pain. I hope this helps.
