Awww =) He's so sweet in his lil cloth diaper! As for the umbilical cord stub, Wade lost his right at 2 weeks. You can use alcohol pads to help dry it out and it'll fall off faster. That's what my doc suggested.
How adorable! My friend loved RAR as well. That's cool that it snaps down like that!
Mine have all been different - Judah's fell off at 16 days I believe. And it was hanging by a thread so I just cut it and the rest fell off the next day or something.
Just be diligent about using alcohol on it and don't be afraid to get in the cracks and crevices because it can get gunky. I think the more you clean it, the quicker it falls off.
I hate the cord, makes me nauseous.
