If you are having a difficult time getting your child to listen to you or follow simple orders I empathize with you. It isn't easy, someone once said "being a good parent is the hardest thing you'll ever do." However you have to teach your child to accept your authority and the earlier you start the better. There is no need to be harsh or cruel. I think if you discipline your child using these 4 easy ways you will start to see some big changes.
First : You must speak very clearly and firmly to your child leaving no doubt about what you require them to do.
Second : Don't expect your children to be able to do more than they are capable of at their age, in other words set realistic standards of behavior for their age level.
Third : Be consistent; don't keep changing your mind. Once you've given your word stick to it no matter what. It's very important that you and your spouse work on this together don't give in and say yes when your spouse has already said no. Children pick up on this very quickly and will soon be saying "well daddy said it was ok" or "mommy said I could have it."
Fourth : It's important that you say what you do and do what you say, in other words practice what you preach. Always be courteous to your children always say "please " and "thank you" and expect them to be courteous to you and everyone else.
