I completely understand how you feel. I have 3 kids 9, 8, &7. And I'm a single mom. I explained to them and have to remind them frequently that this time I am studying , will benefit them. Video's are my savior. I rent movies for them on the weekends and try to make friday their night. We always do something. No books until they go to bed. I drink a lot of caffine and give them a lot of kisses and hugs!! reward them for being good. And ignore the wrong things (unless they are fighting).Good Luck and remain positive always tell your self you can do it !!!
