I was a child when my parents opened a savings account. I remember putting the checks from my grandparents into that account each year as well as when I was older, putting 1/2 of my babysitting money or other earned money into that account. I was able to pay for a school trip to Europe when I was 18 with my accumulated savings.
I got my checking account when I was 17. My dad and I were both on the account. I was earning more money from several part-time jobs and he also wanted me to learn how to use a checking account and balance the account as I prepared for college.
I still kept up the practice of putting 1/2 of my paycheck into savings and then the other 1/2 into checking (and taking some cash out for spending money). I'm not able to put 1/2 of my earnings into savings now, LOL, but at the time, I had very few actual expenses by living at home and not having a car.
