Dear sir, My age is 46 and my wife age is 41. We have only one child and his age is 18. He is studying Btech. First year. The problem is he always playing game on mobile and he can't concentrate on his studying. After we shift our house he don't have any friend and he never go to out side. Always sitting in house, he never watch tv, never touch the text books, time to time never take food. Always he want to play game only. This situation can we possible to get another baby? This age possible? This is good for my son future? Because I feel he is alone that why he doing like this? Same time he failed 4 subject out of six. If I give advice that time only just studying Books and next day as usual he playing game. Because of this problem we feel too bad and no sleep, too stressful life. How can I solve this problem sir please help me?
