I'll vote for the 'bucket' or infant carrier as well. Although it seems like a pain and you'll only use if for 4-6 mos (more if you have small babies) it makes that 4-6 months a total breeze. Babies sleep pretty much non-stop and don't like to be awakened for any reason. Make their life easier by taking letting them sleep in the bucket and get toted everywhere they go...life with babies the first 4-6 mo's, until they get into a regular nap schedule, can be easy enough because infants can bring their bed with them wherever they go.
We also bought a Britax at 7 mos as the baby grew out of the bucket and have used the Britax ever since the kids were old enough.
Congrats on the little one!
