Enforcing discipline on a child(ren) has no age barrier, as early as 3months is a good time to discipline a child when he or she errs. Consistency is key in maintaining such discipline and sticking to rules and regulations will likely bring up a good child.
In as much as we put everything into God's hand, God will not come down from heaven to instill discipline into the heads of our kids. He gave us a guide in the holy books as to how to raise our offspring.
The holy book mentioned sparing the rod and spoiling the child, the western world is strongly against this method of discipline but in Africa it's quite accepted and in some cases abused. I saw a report some days ago, a young boy was flogged and got bruised by his school teacher. That's wrong on so many levels, flog a child with caution and it should never be on a regular basis as it has its own side effects physically and psychologically on the growing child. I have personally given my kids a stroke of cane just for them to know it hurts and after then I resort to scaring them with using the cane on them. Believe me it works wonders when threatened, they comport themselves almost immediately and say a "Mom, i'm sorry".
Josh my oldest kid used to throw tantrums when his demands ain't met, I didn't have the patience to talk to him then since I was nursing a little baby. I simply send him to his room as a form of punishment, he goes inside and begins to play video games. Ofcos it didn't help. What helped was when I took away his game and TV set, sending him to the room eventually became boring and I had the talk with him and made him know he needed patience in life to achieve anything.
Lydia my second kid once developed a habit of grumbling when sent on an errand, this is where parents need to check their actions around the kids. I was super stressed and without a maid, seeing my kids mess things up after cleaning up usually made me grumble. I first worked on myself Before correcting her.
Esther typically is a quiet girl but loves to sing a lot and very curious as well. She wants to see the result of mixing nail polish and face powder together or what happens if body lotion is mixed with a nail desolver. How ever I talked it never worked, I scolded it didn't get better but kept giving her more inspirations on the next concoction to mix for Mommy. What eventually worked was keeping all potential specimens for her mixture away from her reach.
Prince, he is my sweet little terror. At 3months old we already started having problems when he'd bite my nipples when breast feeding, as he grew older and started crawling he admired electricity plugs and wires, I calmly move him away from them and distract him with his noisy toys especially. Now he colours the wall of my living room with any stray crayons he sees, his older siblings help with the correction most times now and keeping him safe away from electricity.
Generally, what has kept me in charge and keeping all under control is my consistency, I never slacked in making sure they abide by my rules and letting them know the consequences. Usually, it's also good to allow natural causes to teach them life lessons. E.g, when they refuse to their homework they fail. However, if your child does not seem to be learning from natural consequences set up some of your own to help change the behavior.
It's good one lays a very good foundation of discipline Before they reach the teenage years as it'll become more difficult to impose rules on them since they are gradually becoming aware of their rights.
It's quite impossible to know it all when it comes to choosing the right punishment to a broken rule. Please share with us your unique method of correcting your kid when he or she errs.
