When you first implement this thing your kid won't believe you. He'll think you're keeping something from him. Let him inspect the thing. When he realizes there's truly and sincerely no way to get his controller, watch in amazement as he...... wait for it....... accepts it and finds something else to do. I've recommended this thing for parents of kids hooked on video games and for parents of kids who can't seem to regulate their cell phone usage. I'll give you two quick examples of how I've done it.
The Cell Phone Teen
It worked. The daughter had her phone in on time virtually every night. She was a minute or so late one night but it only happened once. She didn't enjoy seeing that "22 hours" on the timer. Now here's the craziest part... her parents said the first few times they did this she pouted a little in a typical teenage huffy fashion (that's a word, right?). But, because those actions didn't change the outcome of the situation in ANY way, she stopped after a few days. Remember, kids are more resilient than we are. They can adjust to a new normal. This young lady accepted that her pouting wasn't accomplishing anything and eventually gave it up. Mom said it took a week or so but it eventually became a fairly painless part of her routine.
The XBox Kid
We did the same thing. The controllers and the power cord for the XBox had to be in the safe by 8:00 every night and there was a chart next to it but it was a bit different this time. The timer was set for 22 hours EVERY NIGHT. Which means he only had access to it for 2 hours per day. If the controls were in the safe between 8:00 and 8:05 the timer was set for 23 hours, giving him 1 hour the next day. If they were in the safe between 8:05 and 8:10 the timer was set for 46 hours, meaning he'd lost it for a day. You get the point. So even if this little guy got home before mom (which he did), he couldn't get into his XBox controllers or power cord.
The main problem this mom was having was the she caved after he hounded her enough. She knew that. I give her a ton of credit for being willing to admit it and this little device was a life saver for her. It allowed her to follow through but more importantly, because she wasn't struggling so mightily with follow through, it allowed her to actually see how powerful follow through can be.
One other note: if you do this, don't hound the kid. Part of learning responsibility is learning to do things without having to be nagged or badgered into it. Set the expectation that the phone is in the safe at 9:00. When it's 8:58 and she's still on it, that's not your concern. She knows the rule. Set the timer based on when she puts it in the safe. If she's 10 minutes late as long as you stick to your chart, there's absolutely no need for a lecture. Stay calm. Don't be mad. She knew the rule, she broke it, she pays the price according to the chart. You don't need to lecture her on responsibility. The Kitchen Safe keeping her from her phone is doing that for you. If you can be disciplined enough to stay off her back about it, this lesson will stick because you don't get in the way of it. Again, DON'T GET MAD. What do you have to be mad about anyway? She's the one who's now without her phone. Don't inflame the situation by piling on.
The specifics in your home will vary but regardless of what it looks like, I strongly suggest this thing. You'll be amazed at how freeing it is to have something put away with no option to get it back. For some, it's the kids. For others, it may be the parents. Maybe mom and dad need to put their phones away at dinner or during family game time (which you're totally having every week... at least that's what it says on your Facebook page... although I'm beginning to suspect that maybe those profiles aren't a totally honest reflection of real life. Nah, now I'm just talking crazy!). Maybe this little contraption will take one or two of your daily struggles and make them a bit easier. Or maybe you'll go really bonkers and actually use it for what it was designed for... junk food!
I'm not being paid by Kitchen Safe. I don't know them, they don't know me. I'll make no money off of endorsing their product. I'm a Marriage and Family Therapist who makes recommendations when I see something that can help your family. Go get this thing. It's crazy effective.
