hi my son is intelligent but he never listen anybody's advice

hi Kaushik ji! make sure when u speak to your son , the tone is soft and polite and consider asking his viewpoint and praise him for expressing.. avoid criticizing him if there is a difference of opinion. give options and amicably find a solution by reaching a consensus.. the more u would listen to him, more he will feel he is controlling the situation thereby leading to less power struggles. with love, patience and praise u could handle the situation better. it will be a win-win situation for both.

he use to ask for mobile for playing games should I give him?

kaushik Ji! talk to him politely and discuss the long term impact of playing games on phones . do some research with him. infact u could record a video and show it on TV or computer which talks about the impact on child's eyes, brain and his overall development. with consensus delete the games on your phone. tell him u could have done that without informing him as well but u wanted him to do that on his own. instead give him equally interesting alternatives by spending time with him. take him to the park or join a sport with him. play chess or other​ games which improve memory and concentration. hope this answers your query.
