@daniellemybelle: I got some baby doll cloth diapers from Target last year. They are white and yes, they have pink velcro tabs, but the main diaper is white.

Rumparooz also makes doll diapers that come in a two-pack for $10...you can get lots of different combinations and they fit a wide variety of dolls. http://www.kangacare.com/Buy-Rumparooz-Doll-Cloth-Diapers.html

Also, I hate the Baby Alive diapers. They are disposables since the Baby Alive supposedly poops/pees in them, but you absolutely can't reuse them with other dolls because the closures only work 1-2 times. It's really frustrating.

@avivoca: I've seen those rumparooz doll diapers. Really cute options!

I think I saw a plain wooden doll bed at ikea. Newborn size neutral bibs would work for larger dolls.
For a bottle maybe find out where animal rescues get the tiny bottles they use with orphaned animals.
As for clothing, I'd love to know. I've looked and haven't found any to fit our dolls.
