We have a chore chart. It is pretty involved but it works for us and it worked with the foreign exchange student and my 21 yo who came home this summer from the Navy. .
Each day of the month has three chores assigned to it. CAT, DOG, KITCHEN
Each child has a colored marker. Purple, Blue, Pink 3 kids
On the first day of the month my 15 yo gets Cat , then day two she gets dog then day three she gets kitchen. I mark the calendar with day 1C,day 2 D,day 3 K in her color, purple.
Then on the first day of the month my 12yo gets Dog, day 2 kitchen, day 3 cat and CDK is written in pink
My 9 yo gets the same only he starts with the kitchen his CDK is blue
Day four is just like day 1 for all of them. This has been in effect for almost 7 years. My kids do not fight about whose day it was or who did it last.
I look at the calendar and say Jessica, your on cat, do the cat chores. Or whatever they are on.
The chores include
CAT: feed, scoop litter, water every day
on Saturday Downstairs bathroom, laundry room(where cats' box is), upstairs hallway, stiars
DOG: Feed, water, take outside and tie out, pick up poops
On Saturday piano room, dining room, foyer
Kitchen, all kitchen duties, setting the table, washing dishes, loading/unloading dishwasher
Saturday kitch person also gets the breakfast nook area and the family room.
On Saturday they all dust, vacuum, pick up, wash windows in their respective rooms and they all know how to do the laundry.
Start slow and teach her. Be in the room with her and say "this is how we do the dusting/vacuuming/toilet."
You can hide things in the rooms she is supposed to clean too. Sometimes I go around on Friday night and put quarters under things that need to be dusted. Any money they find is for them to keep.
My son is 9 and does a pretty good job, but he's been doing this since he was in diapers. If any of them do a half a$$ed job I make them redo it.
No I am not a clean freak. Today there are dishes that will sit there until tomorrow and my husband fed the dogs. But my kids do know when I mean it and they need to get the house clean.
Take the fight out of it and let the calendar do the talking. Give the 3 yo a dist rag and let her have at it. That way she's helping.
