I'm just looking for some input from experienced parents out there. I've already gotten a carrier (2 actually, an ergo and another sling-type) and I'd really like to use that as much as possible.

The items in question are the carseat and stroller. Of course, I am going to get a carseat, I'm just not sure which one. I'm currently planning on getting a convertible seat - the kind that can face backward and forward and can grow with baby from newborn to toddler. I don't really want the infant kind that people take out and carry around. Like I said, I'd prefer to hold/wear baby than leave it in the carseat. I've heard lots of, "You never want to wake a sleeping baby...," but I'm just not sure, especially considering the recommendations that say not to leave babies in their carseats for longer than necessary. So, am I making sense here? Or stubborn and silly (and naive...)?

Next, I don't plan to get a stroller until at least 6 months or so. Because I don't really want the whole "travel system" thing, I'm planning on getting a lightweight umbrella type and using it only occasionally. I live in an area that isn't really walking friendly. My neighborhood has paths and such, but no where that we'd walk for errands or anything like that. So, the stroller would have to go in the car first, to where ever we're going, and then be unfolded, etc. Does that make sense?

Any recs on either of these (carseat or umbrella stroller)?
