Second baby must haves...

We are expecting our second little one here soon and not really sure what we will need this round. Obviously we will have the basics, but was there anything you used the second that you didn't even consider for the first?

The babes will be about 2yrs apart. We are hoping to transition the 2-2.5yo to a toddler bed by the time the new baby will move out of bassinet. We can't decide if it will be too early. Any tips for "big kid bed" transitioning would be great.
