We finally decided on a stroller and a carseat so I am feeling a little more prepared for the baby. Thanks everyone so much for your advice and suggestions.
We went with the Phil and Ted's stroller, which can be a single or a double stroller, after realizing that this was really the only thing that was going to fit in our trunk. While I don't love everything about it, it is pretty cool and Harper seems to really like it. We decided to take it to Santa Monica yesterday to test it out. Now we just need to get Harper a bed . . . (see next post).
