This is just a short chunk of things copied from my bucket list. Kids don't mix well with the above activities.
Don't know about Amsterdam: they do have kids in Amsterdam, but perhaps you mean "a year living high on drugs surrounded by prostitutes"? No offense - just wondering why it would be incompatible with kids.
Antarctica: again, why not. Depends on what you want to do there. Also you can do some things when your kids are older.
Even taking a few months off doesn't seem impossible, with a supporting spouse. I think there are lots of parents who go away to remote locations for work (truck drivers and oil rig workers for example).
They'll pick up a foreign language (even though Dutch is not the most important one) and see a different culture.
After thinking long and hard about it, I agree with your premise. Kids should be compatible with the activities I still want to do in my lifetime. Thanks for the advice.
