First of all, don't expect so much.
They are still little. It will get better soon, though!
Secondly, only assign a couple of things that are age appropriate & the
younger one should have a bit less taxing items.
Third, a few things should be expected (put away your toys, pick up your
socks, put your shoes by the front door not in middle of room etc.).
We help our young ones get ready for bed. It's all at once & it isn't a fight.
We get the pajamas out for the 5 yr old, have the get dressed if they can
then all at once we pee, floss w/floss picks, brush our teeth then go into
their rooms for either a goodnight story or tuck in bed/kisses etc.
We used to have a problem w/the oldest putting clothes into the hamper so
for awhile it was kept in the bathroom to make it easy!! Undress for bath &
drop into laundry hamper that is right there in bathroom.
Chore charts work better for older kids (child development) but you can
try elementary ones for this age just make them basic & w/only 3 things for
the five yr old & 7 things for the older child.
The things we "expect" our not too overly loaded & age appropriate. For
example for the 5 yr old (put toys away, put your shoes & backpack by the
front door, take silverwear & napkins to the table).
For the 7 yr old (make your bed, fold the towels, set the table...that's it..not
a million more things. Add a thing or two but not 20 items just yet).
These things are expected. They can complete them because we don't over
exert or expect too much.
Then things to earn extra money? Dust, 7 yr old can help dad collect garbage from the cans in the rooms to help take out to the big trash can, both can help get recycling together, help wash the cars, help mom unload the dishwasher (the youngest gets the plastic cups & tupperware so he doesn't break them), help mom shovel dog poop in order for mom to mow,
sweep, vacuum.
With bedtime routine, I make sure if we have after school sports or activites that they get a few mins of downtime w/the family to sit & watch 20 mins of tv & talk. Then I make their bedtiime routine all together in the last 15 mins before bed w/tuck in time & kisses. You could add reading a bedtime story here but we do ours before bed out in the living room.
Remember to make things age appropriate especially your expectations.
Help facilitate like a reminder that's it's time to get your backpacks ready & by the front door etc.
Separate things that are expected (caution, do not overload here, keep in mind they are kids & their ages) & things that are "extra" in order to earn money & teach the value of work/save/spend. (It's much harder to spend hard earned money.) ;)
You can have the 7 yr old be in charge of feeding the pet & the 5 yr old can help. However, I always double check there's food/water in the bowl so poochie doesn't go hungry/thirsty. This has come in handy several times. ;)
Generally they are pretty good.
Remember to make your list for the 5 yr old shorter.
They help us set the table. I take breakables to the actual table for them.
What seems to work with kids is having a few age related expectations then having some extra duties to earn money to have just for them to spend.
Btw, we take birthday money in cards to the bank. We use the chore/earn money system for some extra cash to spend on an inepensive toy so they can see how hard it is to earn money for things they want. Then they realize why mom & dad need to budget their money, allocate it & make it last. Imperative lessons for the future.
