Let’s get one thing out in the open, right from the start:
Curriculum is there to work for you. You are NOT bound to work for it.
No, you do NOT have to follow it, verbatim, as-prescribed, day-by-day, task-by-task. No, you are not going to mess up your child’s entire education if you veer from it from time to time. No, you are not “ruining everything” if you ditch it after six weeks because it’s making you or your child miserable.
