D.,
I am a mother, a grandmother, a teacher, and a writer of parenting columns.
I am guessing, but I assume you are trying to get your child to pick up toys, come to meals, get his coat, brush his teeth, and other similar everyday tasks. I also think he is tuning you out to keep your attention on him. Parental attention, in any form, is a powerful motivator, far more powerful than stickers or candy.
To be effective, you have to stop all forms of nagging, reminding, and second chances. And, any discipline needs to include withholding your attention. To begin this, I suggest that you cuddle on the couch and read a book to your child. When the book is finished, with your arm around him, you say, “John, there has been a problem. When I tell you to do something, you don’t do it. In our family, when I ask you to do something you need to do it. Do you understand? Okay, we are going to practice that now. Then you can go play.” Then you tell him to pick up a specific toy and put it away. Tell him once. My bet is that he will do it because you are paying attention to him. Give him a big hug and a thank you. Tell him that is the way things work in this family. Don’t gush! If he doesn’t do it, don’t let him play. Bring him back to the couch and say, “You can play when you are finished.” Have a book to read or some picking up to do so you are not paying attention to him, but you are supervising him. When he finally does what you ask, give him a hug and thank him. Tell him he can go play now.
Do more practices over the next few days. Always do them when you are feeling cozy and can spend some time with him before the request. Give no reminders and keep the thank you calm and simple.
If he does not do what you tell him, take him to the couch and say, “You need to do what I told you.” By withholding your attention, he is given the responsibility to do what is necessary to get that attention. Keep your directions simple and meaningful.
After a few days, begin to tell him how helpful he is. When you thank him, say, “Thank you for doing that right when I told you.” Tell other people that he has learned how to do what he is told. And, remember, if your child is not getting quality attention from you on a regular basis, he will find other ways to keep your attention on him.
Good luck,
D.
