Yes, I would say over the last several thousand years, since agriculture, both parents stayed home (on the farm/lord's land) and the kids helped them work it. Having one or both parents gone any substantial amount of time is a completely new phenomenon outside death from disease or war or something like that. Industrialization over the past 150 years or so has gradually but completely changed how humans work and I think we're still getting accustomed to it as a species. One of the nice things about remote working now is we're returning back to working at home / on the farm, which is more "natural" than both parents going to the office/factory.
