When I was in college I had an hour plus commute so one thing I would do is record myself reading my notes and then play the audio while I drove to campus. You may find it useful to do some sort of voice notes with your own study materials and then you can listen to it during the day (one headphone in while you do chores or if your little one is contact napping).
I would also see if you can get out of the house once a week for a few hours without the kiddos. Go to a library to study. No distractions there and that’s dedicated time for you to study.
Establish a good bedtime schedule, that is the best time after kids are settled to have peaceful study. Try to tire them during the day if possible
