Ohhhhh TCN. We had a wonderful few threads about exactly this. I want you to search the thread FIRST-TIMER 2012 (i got wonderful advice regarding time management there! Also search the thread STUDY TIME TABLE OR GO TO SNW groups, join the group LLB Mommies and see under there for threads that might touch this subject.
I was also studying fulltime at Stellenbosch when i was pregnant with my daughter (she's 4 now), i graduated when she was only 6 weeks old.
Feels like i'm telling this story over and over again. But please, search the above threads and also numerous other threads on "study time table", "Time management" and key words in that regard, you'll see lots of threads on issues like this.
I'm assuming you're a single mom? Because if you are not it's time to have a talk with your partner. If you are ready to study and your daughter is still awake, your partner should be stepping in there. He should definitely keep the little one occupied or put her to bed or something. Your support structure is very important! If you're a single mommy, well, there's lots of other single mommies on here, such as myself (well, not really because i'm sacked up together with my fiance), but we can probably give you a few tips.
I can start by giving you the one tip that i give everybody because it works FOR ME. You can try it and if it doesn't work nobody will be losing sleep over it.
A good supplement is the key to MY day. We are so busy, few of us has time to sit done for a decent meal with all the nutrients that we need to keep in the game. My doctor advised me to use DS-24. A multivitamin. He uses it himself. I usually eat everything on sight, but it's not always healthy, but since i've been using this vitamin i feel like i can stretch my days longer into the evenings, and i definitely get up feeling like i've SLEPT.
Getting your diet or your energy levels right is probably what you need to fix first. Believe me, you can have the fanciest time table and the cutest study methods but if your energy levels are low you're screwed.
Now go on and read the threads mentioned above, wait for other ladies to give input and then we dive into your problem.
PS: I'll be 29 in Aug this year, so scrap the "when you were young" part
You can do it, like the rest of us!
