Stop asking and start demanding. You don’t need to encourage them you need to show them and tell them exactly what you expect them to do. Then don’t let them leave the house or get privileges (like having a cell phone, using the computer for anything except supervised homework, a car, or watching TV or listening to music or participating in sports or whatever else floats their boat) until they do what you tell them to do. If they currently get an allowance, stop that at once, until this situation is rectified.
Hold a family meeting and make sure that your husband or SO is 100% on board with you about this. If you don’t see eye to eye with your spouse about this situation, then the battle is already lost. Take them into the kitchen and tell them and show them exactly what you expect them to do, no matter how much they moan and groan. You’re the adult here. It’s your home, it’s your rules and you need to teach them how to grow into a responsible, respectful adult.
After you’ve told them and shown them exactly how you want things to be done, draw up a chart that lists each child’s name with the days of the month and each of their tasks written up clearly and concisely and put it right on the refrigerator door so that everyone can see it. Let them know that they not only need to finish the task at the appointed time and day, it needs to be done to your specifications and satisfaction and they need to mark off each task that they do. This will not only get them in the practice of doing the task (so they can’t claim to have forgotten) it lets you know for certain that the task has been done. Let them know that you will be checking up on their work to make sure that they are actually doing it. Immediately start saying Thank you, honey” to them when they do the tasks correctly. If they refuse to do the tasks, or don’t do them correctly (due to laziness, rather than some type of developmental problem if they have any) remind them that they won’t be going out of the house or getting any other privileges until they do what you expect.
There is no need to yell or threaten them. Explain to them that because they are members of a family that lives and uses this house, that you are providing for them, it’s everybody’s responsibiliy to pick up the slack and carry their own weight and that you are not anybody’s servant. Let them know that you love them and want to teach them how to grow up into responsible adults who people will respect, but right now you realize that they have been allowed to be lazy and irresponsible and disrespectful to you and your spouse and your home and you won’t allow it anymore. That’s all.
Try not to let yourself get flustered or start crying or start yelling, that will make this whole situation worse. Also, do not be wishy washy and make sure that you and your spouse are 100% in agreement about this, or else this won’t work. Just be very plain and matter of fact about how things are going to change in your household and what you expect from them.
If one of these kids balks and starts making stupid statements like, “You suck and I’m not going to do it.” Calmly let them know that you will be contacting all of their friend’s parents, their teacher, their guidance counselor and their pediatrician and letting them know what they (the kid) said. Hopefully you won’t have to resort to that, but put that threat out there and then follow through with it if you have to. It’s not like any one of those authority figures can actually do anything about it, or punish them, but the embarrassing thought of having all of those people know what a lazy lout you are is not very appealing to most kids.
Good luck : )
P.S. Start watching (rent them if you have to) episodes of the Supernanny with Jo Frost. She knows her stuff, she’s no-nonsense, she’s kind and she gets results.
