Of course it is okay to discipline your child. That is how they learn the difference between right and wrong. When I was younger my mother would spank me with a wooden spoon which now I don't think is right. I believe you should love with your hands and spank with your hand. Also she would spank me and then hug me and let me know that she loved me and she wasn't spanking me just to spank me there was a reason. You can't just discipline your child and not tell them what they did because they will just keep doing what they are. In the future when your children are grown they will look back and be thankful that my parents cared about me enough to let me know when I was doing the wrong thing. They will also understand as they get older that some of the things they were doing could have made them get hurt. Just make sure to let them know just because you are discipling them doesn't mean you don't love them anymore.
