Wanted to share my experience here. Often we are leaned to give our kids favor, and tend to keep them in comfort. But at some point, we need to leave them and learn from their mistakes. That way, it will make them disciplined. I am sharing my experience here. So my 10 yr kid who reads in Standard 5, is not very disciplined yet, and keeps forgetting things. Sometimes he would forget his school locker key, sometimes his pouch of pens / pencils and will ask me to bring after he boards in the school. Though it did not happen a lot of time, but it happened 2-3 times.
And today, he forgot his water bottle for the first time and then asked me to bring. And I strongly denied to do that today, though from my heart, I was feeling bad. But this is the only way to teach him that he needs to take care of his things.
So I decided, not to get him today and use his own ways to manage. This way, he will learn two things : to manage in odd situation, and then to be disciplined to check his belongings before he leaves home.
We need to stop giving comfort to the kids at some point so that, they need to be independent on their own. If you are not doing this yet, then please do it asap. By doing this you will only help your kid, so don't take by heart by act by your brain.
