My friend was this way. She started the kids learning skills at a young age.
It went sort of like this.
The little bitty kids, age 5 and under, were helpers to the other kids. They could empty the silverware and sort it out and put it up. They helped gather the smaller trash cans and helped the bigger kids gather the trash. They folded washcloths and sorted socks. They were learning to do a lot of helping.
The little kids (age 5-8) were the big kids (age 8 and up) helpers. Once a kiddo was baptized they were allowed to have more responsibilities. They were cooks helpers and often make whole meals with an adult supervising.
By the time the kids were 10 they could make whole meals by themselves without assistance. They had little kids helping them and they were competent.
Her hubby got home at 4 and she got home about 5:30 to dinner going down on the table. The kids also had assigned rooms they cleaned daily same set up, and she never had to wash a dish or clean up after eating. Since she had taught them and had specific lists of things they had to do to be done they always did it the same way and it was done to her standards.
Perhaps it's time to assign more chores out to kids and hubby.
He had hubby overseeing everyone when they got home from school and he started them off doing their chores.
For instance, one older kid was in charge of the dining room. They had a little kid as a helper, it was their job to teach the younger child how to do the room the right way. Not be their boss in any way but to be a teacher.
The dining room went sort of like this.
The dining room is clean when:
All the plants have had a little drink.
All the book shelves have been wiped down with a dry rag sprayed with some Behold.
The table is washed clean and dried off.
The chairs have been wiped down and no food is left on them.
The floor has been swept, dust pan used, and mopped if there are any dirty spots.
