I have a 6 year old, 2 year old and a 1 year old. I take care of my mother and have been going to school this last year.
Here are my tips
Dont be afraid to study in the bathroom. Run the tub if you have too!
If you are married- setup a dont bother me schedule
If you have a vcr and access to netflix- order the kids a movie once a or twice a week and during that time study. Keep the volume low if you are in the room with the kids and dont face the movie
Dont feel guilty if you study and feel like the kids are not getting enough attention. The truth is - you just feel guilty and they most likely will not be phased.
Keep a tight schedule in your life- use a planner!!!!! I know with kids keeping schedule is almost a joke- but try. Setup hours that you can study - like an hour before dinner then make dinner and enjoy time with the kids at meal time, then study again before baths or bed. Keep a tight bedtime schedule - so that if the kids go to sleep early enough, you can have special quiet time at night.
Try to study in your free time instead of watching tv. Maybe allow specific programs you can watch. I know I had 2 shows that came on 2x a week - and I made the time to watch them so I could call it "me" time. All other time was studying. Sacrafice some of your own pleasures so the kids are not losing so much time with you.
I would also setup a reward system for youself. When you set goals- reward yourself. Or you could reward the family like going to the park for a picnic or going to a movie with the kids. This will also involve the kids in your studies and they will be excited about how you do in school.
I also made flash cards and had my 6 year old hold them up for me when I would quiz. This worked in 2 ways - one it involved him for a good 5 minutes before he got bored. 2- once he realized it was boring he would go play and leave me alone in fear of having to help mommy with her boring work again. LOL
Dont expect perfection (AND I DO NOT MEAN TO OFFEND ANYONE WITH WHAT I AM ABOUT TO SAY) - being a full time parent plus going to school and running your life is HARD!!!! I envy the students who get to go to school and who do not have young kids. I am sure there life can be just as complicated as our lives- but in different ways. That said- being a parent and student involves being in 2 places at once most the time- which is not possible. So, be willing to make allowances for when you fall short in schooling or as a parent. We are not perfect and striving for perfection when you have a full plate is almost impossible. Set realistic expectations for your situation and dont compare yourself to students who live at home with mom and dad and only go to school.
Remember study as often as you can. I know there are many times in my life when I think- whats the point. I feel like a bad mom for not spending enough time with my boys and a crappy student if I dont get a 100% on a test. I want to throw in the towel - make myself a gooey hot fudge sundae and have a long over due cry.... But I remind myself - that crying wont fix anything and that even if I spend 3 more mins studying that is knowledge gained. It will be 3 more minutes of something instead of nothing. And if I am stressed bc my studying is chopped up in 15 min intervals- I remind myself that most people tune out of studying after 20 mins of straight concentration and that I am gaining more by choppy study work than if I spent 2 straight hours studying and then saying "WHAT IN THE BLANKITY BLANK DID I JUST READ?"
