Quoting Lovin'mylil'man:" I am a really patient person i dont loose my cool that often maybe i should go ahead and start giving ... [snip!] ... giving one warning and the its punishment time what method do u think works best for a 20mnth old becuz time out isnt working"
Every kid is different but I've never done the "corner" thing with my son. Instead, I make him go to his room and shut his door for 5-10 min. We call it quiet time...sometimes he still throws a fit, sometimes he just goes in there and plays, but whenever I tell him he can come out we talk about what happened. Its a huge attitude difference from the time quiet time starts and ends lol.
When we are in public I let him be his own person. I'm pretty laid back I guess, if he wants to get down and play with toys I let him. And if he wants to walk I let him do that too. Only if he starts acting up I let him know that he will have to sit in the cart.
We have pretty great communication.
