I don't think I have enough stuff in my diaper bag..

Or maybe I'm just missing out on enjoying the lightness before the baby comes and it inevitably fills to the brim..?

In both my bag and DH's (Mr. "I'll never cloth diaper!" had to have his own bag...)

I have a couple prefolds, two extra covers, and a fitted (plus an AIO in DH's)

extra snappi 

tube of Grandma El's

pack of disposable wipes (we got them as gifts and figured we'd use them until they're gone)

baggie with cloth wipes

wet bag

spray bottle with diaper lotion potion mix

two extra onesies 

burp cloth/light blanket

 

I must be missing something, they're so light!

Don't worry, you'll fill it up soon enough.  It'll get random toys thrown in as well as other odds and ends (nursing cover, burp cloths, baby sun hat, paperwork from doctor visits, your wallet and keys, etc.).  Just remember to change out the spare clothes every now and then.  I had extra newborn onesies in mine for 3 months, long after he'd outgrown them.  You'll find with CDing that you don't have many (if any) blowouts that require a wardrobe change

In addition to what you have, we keep: changing pad, baby legs, sun hat, sunscreen, pacifer pod, teething gel, lip gloss/compact, camera, nursing cover, bib (the cloth kind are great for spit up, especially in the car), and my wallet.

We also have:

Hand sanitizer, mini first aid kit, emergency paci, Wet Ones, LOs sunglasses, and some of the other stuff already mentioned. 

When he used to nurse 24/7 I also kept some magazines in there to entertain myself.  

I agree- it will fill up fast!
