New resident from out of state

I am relocating from the midwest to Walnut Creek in the coming weeks. I am the parent to a 12 month old daughter and expecting baby #2 in March. I am seeking advice on the following:

Walnut Creek Pediatrician - for my one year old and baby on the way. 

Walnut Creek OB/GYN - I am having a baby soon and would like recommendations. 

Child care!

any recommendations to this newbie would be appreciated!
