Here at our home, our 18 month old knows what it means when he is in his corner. We have a corner in the living room that is the designated "naughty spot". It is used for both boys. I do not send them to their room, because I do not want their room to be a place of punishment. Their room is for sleeping only. Their toys are not in there either for that matter. But I definitely do not think that 2 is too young to punish. I also go by the rule of a minute for every year they are old. They are to stay in their spot until they are "released". They also get time added if they do not stay put. My when my four year old is way out of line, he has to stand in the corner with his nose to the wall with his arms fully extended and palms of his hands completely flat against the wall. That is only used when he is in really big trouble, or won't stay put when he is placed in his spot.
I also am a firm believer in spankings. They are only given out when they are doing the worst possible things: not listening when they are in a dangerous situation, such as parking lot, getting to close to the road, playing with outlets with things plugged in, etc. They are not given for the smaller stuff. I won't spank in frustration either, and I will tell them why they got spanked as well. I am one who is not ashamed to spank my kids in a store either. For instance my son was standing next to the cart at
walmart and decided to run off. He made a mad dash for the exit door. He is four, he knew that was wrong, and did not stop when I yelled after him. The greeter stopped my son before he reached the door, and when I got caught up to him, I had the baby with as well, he did get spanked. I got a very mixed response. It was explained to him why it was happening, and there was a debate right there in
walmart between the other customers. I was yelled at, and I simply looked at the woman and told her that unless she wanted to raise our six kids, she needed to shut her mouth. I also have to add that 99% of the time they are all very well behaved, but there are the days they get a wild hair up their hiney, and it needs to be addressed.
I know that was a bit of a ramble so I hope it helps.
