I'm a single mom and my son is in every sport there is, you can do it I have done it. Its not easy the best thing I can say get a rountine down, If you make them go to bed at 8 and when you get home spend time with them, cooking have them help make it fun and at the same time your spending time with them, have them help you study (flashcards), just remember when it gets hard and you want to cry, crybut then look at each of them and you will know why you are in school.
