Our two year old is a screamer. He screams when he's happy, when he's sad, mad, excited, whatever. We have tried for 18 months to get him to NOT SCREAM, but nothing worked. Finally, we just put him in time-out every single time he screamed. Within 3 days, the amount of screaming in our house had decreased drastically. We do time-outs about 5 times a week now, for throwing toys or when he screams just because he knows it pisses us off.
Anyway, point is, time out saved my ears and my kid, because had he kept the screaming up I'd have killed him. At first glance I thought this product was ridiculous, but, my son does NOT sit in time-out if his daddy puts him there, so I thought this would help. And then I decided to snag a second one for the diaper bag (because that's our newest battle-learning to behave when we're out and about.) If it works, awesome. If not, I'm only out $20. If it ends up he LIKES the stupid thing and starts trying to get time-outs, I'll just sell them. There's gotta be some more time-out and random-crap loving parents out there who don't know about kidswoot, right?
