How to balance stress from work when I am home with my child?

Draw a thick and strict line between work and family no matter how hard it may be. When you're at work, try to focus as much of your attention so that you can finish your tasks at hand and get home on time or bring work home. And when you're at home with your family, do not bring work along - rest, spend time with your family and relax. In my old workplace, my ex-work partner is a father of 2 and he used to get called up during weekends. I felt bad for him so we decided that if such things happen on weekends, I'd handle them and in return, he'd cover for me when I went away for long holidays. And when he was on Child-Care Leave or Child MC, I'd tell my supervisors not to bother him, instead to ask me about his work so his days with his kids will not be uninterrupted. If you have a good friend/partner/colleague at work that you can count on, perhaps you can come to some sort of an agreement.
