P.-
Interestingly, I have that analytical personality and am VERY type A, and I have no routines. It completely blows people away who know me that I am not the parent who had everythign scheduled.
I think you learned some valuable lessons from your childhood about how not to parent - as long as you don't fall into those habits, I think you'll be fine with or without a schedule. I've learned that instincts are a powerful thing.
Having cancer right after the birth of my second child also taught me that being present in their lives is THE most important thing a mom can do. Yes, you need to provide structure, be a good mentor for life's lessons, etc. But, engaging with your kids, providing discipline and support go a LONG way. Because of that, I don't want to get too scheduled that it overtakes our lives and makes us forget that it's the people in our lives that are truly most important, not the activities or things.
Maybe when my kids are older I'll feel differently, but for now we survive on that mantra.
Good luck!
