Time to make a change again?

Counting my fingers, this is the fourth year I work as a mom full time.

You are correct.  My big one is already 8, I should be a mom much longer than that.  I mean I had dedicated to stay full time at home since 2010.  In the last four years, I worked as a part time/ freelance market researcher, and occasionally on some other jobs, like marketing, blogging, even as awkward as 'name-giving' to a company.

Anyway, my little one will study primary 1 in coming September.  I am wondering if I should join the workforce again, full time.

It is not an easy decision.  First, I am not sure if my little one can handle the primary 1 well.  Should I just stand by?  Second, there are so many ad hoc events every week, not to mention all those after school classes I should send them back and forth.  Third, working full-time means I should compromise my flexibility now.  I don't want to skip or even quit my piano and French classes.

Sigh! Let see.
