A mom has to stay home a lot to have enough time to homeschool. Interruptions from others. Be firm and consistent with your friends and relatives. Establish time for them, but your students are the first priority, not your friends. Eliminate unnecessary school work.
Textbooks can have a lot of extra work that is boring and unnecessary.
You don't have to work for the book. Look at each of your children's books. Cut out or cross out unnecessary pages. Get over your desire to finish the book. Teach the chapters and do questions orally to eliminate a lot of student paperwork.
