I found I was a MUCH better student after I had my son, because I *had* to be disciplined. I only had short windows (naps and after bedtime) to do my studying/hw/writing so that's when my work HAD to get done.
I'm pursuing a very loooooooong degree path, and to add to it, I've taken a year off here and there to work. The biggest trick I've found when coming back after a break is to only do ONE class my first quarter back. I also never take a full load. I've tried it, not enough time. So I max out at 2 classes, instead of 3. But that first quarter, just doing one class is the best way to ease myself back in.
Most CC's have onsite daycare. I got unlucky and was on a waitlist for 4 years. The U was soooooo much better, because instead of onsite childcare, they subsidized it instead. Sent my son to the most amaaaaaazing montessori preschool essentially for free courtesy of the U.
I personally *love* being in school. For me it's the best alternative: all the benefits of being a SAHP & WP, and nada the drawbacks (I'd be gone an average of 4-10 hours a week, totally doable as far as arranging childcare, and most of that time the school paid fo ritb. There are also only 2 days every 3 months that one really can't afford to miss when a little on gets sick (midterms & finals). All the rest are negotiable (in my experience, even in prenursing/premed classes), and easily made up. Even labs just require a quick email shot off at the prof.
Another thing, I found for myself, is to avoid night classes. I study at night. Sticking a class in there seriously cut into my self and study time.
