Hey Buddha!
I understand you. I have 3 kids myself. I started climbing only 4 years ago when I was 34 when my youngest was 5 (they are now 9, 10 and 12).
But if it is a passion, your wife should understand that and let you climb. At first, you do the less dangerous peaks like Kili, Elbrus, Mt Blanc, Rainier and even Aconcagua. If you feel bad you descend immediately, you don't take any chance. Sure there are always risks but you can minimize those risks by going slower than most and taking more days to climb a route (like Kili in 9 or 10 days).
And between the climbs, you take mountaineering courses, ice climbing courses, rock climbing courses, crevasse rescue and so on. I just took my wilderness first aid training for the outdoor leader and my CPR certification. You go winter camping for a few days. Those courses combined with Elbrus and Aconcagua will get you the experience needed to climb Denali in a safe way in maybe 4 or 5 years.
It's a long term plan, but in 4 to 5 years, you'll have more time to climb and go in expeditions and you'll be closer to your dream of climbing the 7 summits. Putting your dreams aside is the worst thing you can do, it will destroy you. I should have started earlier than I did, don't make the same error.
Hey mc!
For Portillo, look at their website
