Redefine "has to be gone a lot".
Being in school only REQUIRES being gone for the time your bum is physically in the chair in class. All the EXTRAS are just that. Ditch the study groups, library studying, pub crawls, potlucks, SBOs, widely scheduled classes (morning class, 4 hour break, evening class) that you stay on campus for the whole day, extracurriculars, etc.
That leaves MOST students with being gone 10-15 hours a week including commute.
A HECKUVA lot less time than even a part time job.
Now... Babies sleep a LOT. Its in pieces, but they do sleep. When do you study? During the 12-18 hours a day they're sleeping. You only need 7-9 hours of sleep, that's 3-11 hours of studying. Every day.
Its the DREAM "work at home / set your own hours" job.
After you figure out how to study during morning & afternoon naps, and after bedtime at night?
Then add in the occasional study group/ club/ extracurricular / SBO/ etc.
Just make sure Mom has that opportunity as well.
What worked well for my ex & I while we were both in school back when was he got Saturday, and I got Sunday. Meaning he had our son from wakep until bedtime on Sundat, & I had him Saturday. 1 whole day a week for paper writing, research, study group session, boys/girls nights, whatever. We each had school M-Th. Friday was family day. Sat his. Sun mine.
Other student families work out different schedules. But that was ours.
This will be the EASIEST time.
Working 40+ hours? Then coming home & working again? Or 14 hour days being a SAHP w no break?
1000x harder than skipping a kegger or 21 run, or studying in hour blocks at nap time.
