My typical schedule sees me working until 5:30pm, playing with the baby while the wife cooks until 6pm, eating dinner together until 6:30pm, bathing the baby getting it to bed around 7:30pm, then doing various housework, family admin tasks, or evening activities until 9pm before unwinding for an hour and going to bed to "sleep". The schedule is actually more pressured on days where I go to the office and don't get back until later.

My wife does have the opportunity to go to the shop in the morning or afternoon, but it is very contingent on energy levels (sleep is rarely good), baby nap times (variable but better off being respected), baby activity classes etc... . Going to the shop itself can take longer as you may need to suddenly deal with a nappy change or tantrum. It's not reasonable to expect it to happen multiple times a week.
