I have a family and kids, and did when I took my ATPLs. I went the integrated route, and moved away for the year since I knew there was no way
I personally could have studied at home.
I studied 5-6hrs a night on top of the ground school so that my weekends were free for family stuff.
I found that I studied best by making bubble charts of the topics as I went along. Come the end of the topic I had a set of very consise charts that allowed me to revise the complete topic for the exam in about 1-2 hours, so just a quick brush up. I also found it helped me to learn since I was actively learning, not just reading but writing as well.
It works for me and ended up with all 14 at first sitting. Do I still remember it
Did I need 90% of it?
Good luck
