Sorry to hear about your situation. Without sounding patronising and judgemental, I would like to reassure you that being single mother and to care for two children is not easy. Below are some of the parenting tips, you might find helpful. 1. Be firm and consistent with your instructions; 2. Say what you want the child to do, no need to give reasons; 3. Say how you feel if the child doesn't listen to you; 4. Reward for good behavior and take away privileges for bad behaviour (eg. No TV); and 5. Spend time with each child separately by setting boundaries. Best wishes.
