I am a SAHM. My Hubby works full-time and goes to school pat-time at a university.
It is time consuming, for BOTH.
Being a SAHM is a full-time "job." Adding in school, for you, and it is very busy and time management is hard.
What you both can do... is set-up TOGETHER a "schedule" of who does what each day, and "when." Then, post it up on a poster, and so you each can remind yourselves of it.
It has to be fair. YOU have to study too, as does he. AND BOTH have to mind the children and giving them face-time and quality time, and playing with them. An "absent" parent (who is studying or on the computer all the time), is equally "not present" even if he is in the home... because "men" have a hard time multi-tasking doing "their" things/studying PLUS having household responsibilities. THUS, make it organized and write it down... on an "FYI" board.
When my Hubby is entrenched in school work after work, even if he is at home... I am like a Single-Parent. Doing everything. BUT... we talk about it and he has to give time to the home/children TOO. So he makes a concerted effort to do so. It is only fair. The children... my kids... "miss" their Daddy when he is so embroiled in his "work" at home and studying too. So your Hubby has to realize that.
For you, YOU have to study too. If not why bother. School is important.
For my friend, what she did is have a Nanny IN their home, to help, daily. Then that is when SHE did her work/studying. Maybe try that route instead of paying for Daycare outside the home. And, schedule the Nanny for when it is the best/busiest time for you or both of you, and when you need to go to school/study.
OR, yes, make a "schedule" for when YOU will study... even if that means actually LEAVING the house to hunker down at a Starbucks to study. Then, put that down on the "FYI" Board too, which you AND Hubby would refer to. Schedule things, for yourself and your stuff.
It takes organization... AND the other person, stepping-up to their "role" as both Parent and student.. meaning, in the home, Hubby can't just use you as a "default" do-it-all Parent and Wife... while he spends all his home time on the computer. HE has to step up too.
Yes, it is stressful. Thus, you both NEED to work out a plan, a "to do" list, an "FYI" list, a "Chore List" or who-does-what/when list... so you BOTH can address all your responsibilities, in light of school and work.
The kids, cannot reliably be a floating satellite amongst everything while parents are working at home. So, you'll need to toggle off between the 2 of you, for minding the children and giving them face-time and quality time.
And then, who the heck cooks dinner and does the dishes afterward? LOL
Another thing, but important thing, to factor into the whole time-management and child rearing schematic.
AND.. a Mom needs to sleep, too. Hubby needs to have a role in all this, too. A "SAHM" does not get days off nor holidays, nor time to herself. So... create a poster board to delineate things in the home. For you both. The last thing you'd want... is for resentment to build-up or your grades to suffer... and Hubby needs to think about his "wife" too.
All the best,
Susan
