Do you think my 4 year old son is old enough to get a whooping from me?

Try a time out where you pay no attention to him. If he gets up out of the place where you have put him for his time out, put him back without saying anything. He just wants your verbal attention and if you don't give it to him, he'll stop. If it does come to pass that he needs a spanking, by all means go ahead and do so. Warn him before you spank him, and make sure he understands what a spanking is.But hitting your child with an implement like a belt, wooden spoon or hairbrush is tantamount to torture. It doesn't do any additional good when compared to regular spanking with a hand, and it makes the child think you are electing to use a weapon on them. Spank him 3 times with your open hand, and then put him on his feet and walk away.
