Rec. your carseat and stroller

jess!ca

So, I've come to realize that shopping around and picking out baby things is a lot.   I plan on doing lots of research on things like carseats and strollers, but also thought I would check in with you ladies to see what you have and how you like it.

What carseat do you use?  (I'm buying for an infant)

What stroller do you use?

Are they a set?  What are the advantages and disadvantages to this?

There are probaby questions I don't even know to ask...  any recommendations are welcome and helpful!  Thanks!
