Q: I'm pregnant with my second child who is due (exactly) four years after the birth of my first. Do I need to buy a new infant carseat, or is it safe to use the one I used for my first daughter? I know that carseats don't expire for seven years, but have there been major advances in carseats over the past four years that I'm missing out on? What do other people do?Sent by Melissa
