Nice list, looks like you have it covered! With clothing, get a buttload of onesies. So much easier for changing, you'll get through a ton.

I second the steriliser, we have an Avent microwave one that does bottles, dummies and pump parts in four minutes. They're often on special at Target, KMart etc.

Muslin wraps are great, you can never have too many; I use them as spew rags, to put over the pram for shade, lay bub on if we're at a park etc. We never used them as swaddles though, we had a little houdini. See how your baby goes; if he/she turns out to be a wriggler, I recommend swaddles with velcro or those ones where they can have their arms up.

You might also need a nappy bag. Most come with a change mat for when you're out and about.

Happy shopping!
