Worked for one of my children (the older one who is a girl) but not for our two year old boy...at least not yet.

never works

Didn't really work as well as hoped. He would always win these kinds of things because he would outlast them in a passive / aggressive manner.

Time-out is the most effective thing we do with my son, although he is a screamer.

He will not take timeouts, causes increased violence towards me if I tell him "time out". I have tried taking a time out for myself, ended in bathroom door nearly being broken down and 911 call followed.

he will put himself in time out sometimes. it just depends on what mood he is in!! It does not really seem to work.

We use time out for cooling down I generally do not use it for discipline. I have had better results using other methods. Although time out would have probably worked well in his younger years had I known he had odd. He will now remove himself from a situation if he is getting too worked up or upset and put himself into "time out"

it works when her daddy does it but not when mommy does it

I ask if he needs time out and he either corrects the behavior or he doesn't and goes to time out for quiet time and relaxes

It worked but I got anxious and more frustrated. Felt like I was going to explode
