In talking to many people over the years, I appear to be in a very small minority, albeit one heavily influenced by my mentors. I not only did not change my climbing, but I started introducing my son to climbing and skiing at a fairly young age. His first backpack was in the Canadian Rockies at about age 3. Barb dropped me off at the trailhead into the Bugaboos and she and Young Son headed for Lake Ohara. It wasn't much of a backpack for them - take the bus from the parking area to the lodge and backpack a half-mile to the campground. But it also turned into William's first snowcamp (yes, it snows in the Canadian Rockies in summer).
And yes, I taught him technical climbing by the time he was 9 or 10 - and he skis better than I do, as well.
Among my mentors were John and Ruth Mendenhall, both of whose daughters Vivian and Valerie, climbed the Matterhorn at a very young age. John Wedberg was another partner and mentor in the 1960s. His son, Kurt, is a professional guide these days (I ran into him down in Antarctica at Vinson Base Camp). John Harlan, father of John Harlan III, the well-known author and editor of the American Alpine Journal, was another acquaintance who did not change his climbing or skiing (died on the Eiger).
On the other hand, I know many climbers who decided they had "responsibilities" to their families as soon as they got married, often even before they had kids.
The way I look at it, climbing, backpacking, backcountry skiing, and such activities are a fundamental part of who I am. I plan to do them for many years to come, so I consider the risks I undertake and how to deal with them. I would also note that more climbers and backcountry skiers of my acquaintance and with whom I have had adventures have died in car accidents and, at my advanced age, of heart attacks, strokes, and cancer than in climbing. Consider that statistically, half of all Americans will be involved in a serious car accident during their lifetimes (in my case, it was someone who ran a stop sign on a small residential street and hit me right at the driver's door pillar without slowing - "didn't see the stop sign" - even though I was on a 4-lane major street - totaled her car and left mine barely drivable to the body shop a half mile away).
If you have kids, yeah, you have some responsibility for providing for their continued well-being. But that goes whether you are climbing, working in a convenience store (do you wear your flak-jacket?), commute more than a couple miles to work, or just live in Florida's hurricane zone, California's earthquake zone, Washington State's lahar zone, or in New England where they have ice storms and people slide off the roads.
So have you written your will, with provisions for care of the kids? Do you max your credit cards and mortgage so there is no money to care for the kids or send them to college when you aren't there to take care of that? Accidents, natural disasters, and pandemics happen. These are more risky than climbing, even though we would like to believe "it can never happen to me."
Take care out there, no matter what your activity. Know the risks, including the part about driving to and from the activity (and your job and your grocery shopping), take precautions, stay alert, and have that emergency kit close at hand at all times.
Oh, yeah, didn't answer the specific questions -
"did you make up climbing rules with your spouse/partner?"
We used to climb together, until Barb tore her ACL while following Young Son through the trees while skiing - Adults should NEVER follow 9 or 10 yr olds on skis through the trees!
"Did your spouse/partner (if they climb) continue to do so? "
Ummm, well, yes, until the ski incident slowed her climbing - the knee never healed properly, so her climbing is at a lower level these days. But she still goes BC skiing with me, and she orienteers on advanced courses, albeit at a leisurely pace.
"Would you climb with your spouse/partner?"
Yup. Did (look on my website for some photos of us climbing together). Still do some. Barb's a great rope gun when I do top rope or (shudder) "sport" climbs ("Sport climbing is neither")
"Would you climb only up to a certain level? No leading? Or did you forget making up rules and decide you’d just do it as long as you felt comfortable?"
That's what I've always done. Well, I do push things to the slightly uncomfortable level - that's the challenge, after all.
