Check with your kids about what they expect of your possessions in time.I'm not ruling out synthetic entirely, but am attracted to wood, if for no other reason than I already own a bunch of synthetic stock rifles.
I don't mind adding some 'patina' to wood either.
I don't expect the stock to be pristine when I give it to my kids, but it shouldn't be brittle and falling apart like some cheap synthetic might do.
I delivered my Dads pet deer rifle for some one else outside his kids to receive recently.
Much as I like rifles , and Dads memory....
With young kids , just get a quality rifle you like. It will have been yours when heirloom time comes.
That matters more than lock stock and barrel choice.
