I have been amply blessed in this department.
My own mother (who had me after she already had been a mother for 13 years) is the person who inspired me to be a mom. She is all those things you think of when the term "super mom" is thrown out there.
As I matured into an adult, I remember her supporting me in my every decision, even those I knew she didn't agree with. She taught me how to care for my children when they were newborns, and came to my rescue a few times when I just needed that extra help only a mother can give.
