Hospital stay after birth

The hospital I'm giving birth at has a 48 hour required stay after you've given birth. I feel like this is a very long time! I had a home birth with my 1st baby and I just can't imagine why we would need to stay for 48 hours if everything is fine! Have any of you left the hospital early?
