S.D.
I've been there. I hate looking for childcare! But, I've been lucky once I finally found the right caretakers.
I'd suggest checking out Craigslist for nanny shares. These are a little more expensive than daycare centers, but for small babies are a great option as another mom has vetted that this nanny is okay. (If you are new to the concept, nanny share usually means a nanny watches your child and another child at either your house or that of the other child.) - To gauge, we pay ~$10 per hour for our daughter's nanny care and have paid as little as $8 an hour in the past (in a nanny share) in Berkeley. I've heard that nannies are a little less expensive in Concord (~$12-$14/hr for 2 kids, so $6-7/per kid..) but cannot verify.
I found my son's daycare on Craigslist as well, but I did a ton of footwork - calling and visiting - before I found a woman who was in the business for the right reasons and who I felt comfortable with.
So, just to reassure you, I have had my children (4 and almost 2) with nannies (only in shares) and at home daycares because I didn't like the more sterile feeling of the more formal daycare centers. All CA daycare providers have to have taken cpr and child development classes, so you don't need to worry about that aspect, but you will need to validate that you agree with the way they will raise your child and their care style.
Hang in there. You will find a great solution. I wish I could be more helpful with resources, but I'm not sure my other favorites - Berkeley Parent's network and Bananas - are helpful to your area.
