My job is very demanding! My 12-year-old wants me to sit with him, during his exam preparations, throughout the evening! He refuses to seek his father's guidance. Unfortunately, juggling with home and office, I am left with no time to spare. Even when I come early, I am unable to focus on him, as I feel too tired. How can I make him understand that his mom cannot guide him for his exams all the time? I also end up feeling guilty of not being able to spend enough time with him. Would this distance him from me?
