planning for second born

We are expecting our second child 12 weeks from today. Wowzers. 12 weeks. Know what? I have done practically NOTHING to prepare for this baby. There is a tiny stack of a few items I picked up for her with a gift card I had, and I got some awesome hand me downs from my cousin. By this time with the first born, the nursery was painted, the furniture was purchased, baby showers had been had, we were almost ready to go! It amazes me how different it is with the second born. Poor girl is getting all of sister's clothes, toys, carseat, everything. On one hand it's sad, on the other it's fantastic. This means we don't need much at all for 2.0, and the bank will not break like last time around.

I've been trying to figure out what we do need for little sister. Here's the short list I've got so far.

Stuff we need for baby 2.0:

Double Stroller. This is the stroller I've picked out and am trying to figure out how to find the money to purchase. Considering selling a kidney. I found it here for only $300 bucks so that's a great deal! Monitor. We just need a second video camera for our monitor so we can look in on both girls. Love that our Summer Infant Monitor can do up to four cameras! (That means 2 more babies soon, right??)

Diapers. Lots and lots of diapers. And then some more. Two kids under 2. I'm nuts.

What else am I missing? Are there some key things that are good to have with a second born, especially with two so close together? Help!
