Teenagers certainly need to stand on their own feet. Not financially, but in their ability to get their work done by themselves. And help around the chores at home. They can`t expect their moms to do all their work for them.
Have a table of things that are to be done each day, that not only involve doing chores but keeping the `house rules`, reading, etc. Each item has a value, and whatever item doesn`t get done, that amount is deducted from their pocket money.
Extra chores like, gardening or washing the car or windows earn extra.
Have a chore chart, complete with `job descriptions` of all the jobs on the chart.
Even walking the dog comes with a job description!
Keep it to one or two jobs per day.
Everything, from cleaning the bathroom, to dusting/vacuuming the living room, washing their clothes, and clearing the litter box is a `job`.
Helping in the kitchen and organising meals too are `jobs`.
Have a job jar
Put in little slips with the job details:
1) room job: bed making, quick pick up and dusting
2) kitchen job: Cooking or cleaning up, doing the dishes
3) house job: laundry, vacuuming, dusting etc.
Keep tab of jobs done and reward with weekend special allowances, permissions, treats and so on.
