Problems at the hospital with carseats?

Jaqueline
We were recently looking at what kind of carseat we want after a lot of research. We found one we really love and want to get. It's a convertible one so it will last all the way through our babies car seat time, but an employee said that hospitals won't let you take the baby with a convertible seat.. has anyone had any problems with this?! Any help would be great!
