What you (*and many others) are doing is monumental.
There are in fact many who could not have stood up to the test you've already put behind you...you keep on keeping on Cateyes. You have it in you - look where you started at and how much you have already accomplished!
Yes...you are taking away some of your parenting time in comparison to before you started this path. I will take a bet though from reading your post that you are an awesome moma! The measure is not only in your quantity of time with your little ones, the work you are doing is something that will benefit you all!
Do try to accept any
help you can get from friends or family doing stuff with them, taking them places etc and you study extra at that time. And, learn to compartmentalize a little more. If you try to study when they are busy needing you and running around being kids like kids will do - you aren't getting much retention out of it anyhow. Take a text or some notes with you and take your girl/kids to the park and spend the first 15 minutes solid playing WITH her... pretending, being silly, and then tell her you will be nearby while she continues to play a bit longer. Make it a routine and she will get used to it and be getting what she thinks she was missing. Sneak in some of your needed study time for awhile right then. And you don't have to stay at the park for an hour and a-half making it a grand outing. I found out that you can plan fun with the kids in smaller/shorter pieces of time and they are fine with it, but they really value it when they have your undivided attention - even if its not as long as it used to be.
As well, you might break up your study time into a few longer chunks each week with many, many smaller periods. Use a tape recorder in theory class and play it back while you are driving or even, *giggles while you are shaving your legs and taking your 6 1/2 minute 'luxury' bath which is about the standard time all mom's with little ones might get, every time you are on some phone call where you are on hold etc. Tape index cards up around the house with vocab words on them - your kids will feel like they are helping as they quiz you, and learn some new vocab along with you! And - have that social drink now and then. But don't go into avoidance behavior - that will be you, sabotaging yourself. Its hard, but try to get some regular exercise even if it seems piddly compared to what you used to fit in. It will help you de-stress and help keep your metabolism up throughout your long days (and nights heh.)
You can do this. And you just keep loving your children through it, alongside you as you finish this path. Be proud of yourself and dig deep to keep keeping on for the length of time you have left to make this goal a reality.
Ooo rah Cateyes!
