My son, in standard 1, can grasp everything but doesn't have the patience to sit for a minute in one place. How to make him learn patience?

I don't think you can make anyone learn patience because it is a complex quality that comes from experience.

What you want first is to take all the excess energy out of the child. Now there is one way to do that, take him out and let him play in the open to his hearts fill. Be careful, but don't stop him from exploring. Do this for a few days, and you will start seeing a positive change. What positive change you ask, he will slow down. When you ask him to study and allow him some time in the park after completing his studies (An excellent teacher is imperative during this time), do this while gradually decreasing his park time to half an hour.

A child is not a machine but a growing human. Let him be the way he is. Engage him with better interesting play and maybe play some soothing music to calm him down. Avoid many sugars, give more fresh food, avoid loud, fast music post 4 pm. It will settle down. Enjoy this phase with him. Take some time out and play. It will bring in a relaxed state to you and a secure feeling to the child.

In this situation, your son is not getting fun during the learning process. It would help if you talked to his teacher. A teacher can solve your problem by making his/her class full of fun, i.e. learning with fun. In the first week, if his teacher does activities of your child's interest in place of teaching, he will tale interest. After this, I am 100 % sure that he will start to love the class and automatically attend the class patiently.

आप अपने बेटे को सिर्फ 28 दिन तक बैठने का ही practice कराए .क्योक।  किसी भी चीज को 28 दिन तक किया जाए तो वो हमारी आदत बन जाती है। कोई जरूरी नहीं है कि वो इस दौरान वो पढ़ाई ही करे वो कुछ भी कर सकता है बस थोड़ा थोड़ा पढ़ाई करते रहे । और बैठने का practice करते रहे।यह एक psychologycal fact है।  और वैसे भी वह अभी बहुत छोटा है तो ज्यादा ज़ोर भी नहीं देना है अभी उसके पास Time है । बस उसको पढ़ने के मोटिवेट करे

Sir, your son is very young and shall take time to adjust to the academic learning process. Instead of making him feel learning is a serious task, you can engage in conversation with him regarding the various topics he needs to learn, such as asking him to tell you the time by the clock, adding up the numbers and so on. With time, he will be able to cope with the process.
