Forget all about those giant, expensive travel system with their bells and whistles. What you need out of an infant stroller is something safe, something easy to use and something you can fold up and throw in the back of your car. Think simple.
This stroller frame is all you need for your infant. You snap her car seat right into the frame, and you are set. When you are done, you unsnap the seat (very easy) and pop the seat back into the car. It has a little basket for keeping a small diaper bag or a bottled water.
New moms always want those giant strollers, but they really aren't good for much except maybe walks around the neighborhood. They are big and a pain to fold and store. They take up a lot of room in your car. Then when you get them to the store, they are hard to manuever in small spaces and sometimes don't even fit through the doors.
Get this one for your infant, and when your baby is older get an umbrella stroller. That's all you need.
