Albany public library on Marin did have one as recently as a couple of years ago on Saturday mornings. I think that you had to sign up in advance (it was very popular). Also North Berkeley branch (on Martin Luther King) had a Saturday group several years ago. There was a librarian named Star there who the children worshipped and she was involved in reading groups.

The Berkeley Public Library/Central branch in downtown Berkeley has a Family Storytime on Saturday mornings from 10:30-11:00. It mostly runs year round, but they didn't have them during September. They are supposed to start up again on Oct. 4th. They advertise it for 3 yr olds and up, but I've been bringing my 2-1/2 yr old for years with her older sister. The librarians alternate and some are better than others. Sue
Berkeley Public Library has lots of toddler storytimes. The Central branch (in temporary quarters at 2121 Allston) has a Baby Bounce (for 6 mos.- 3 yrs. and caregivers) on Mondays at 10:30. Most (maybe all?) the branches have similar programs. You can call for more information, or see http://www.infopeople.org/bpl/kids/storytim.html. Greg
I take my son to Rockridge branch OPL on Saturday mornings for toddler story time, which is from 10:30-11:00 the last 2 Saturdays of every month.
The Rockridge branch has an excellent program for children (and excellent Children's Services Librarians!) with activities ranging from the Saturday program mentioned above, to PJ story hour and visiting performers (Opera Piccolo, puppet shows, music workshops, etc.).
Re the parent who asked about libraries with story times on Saturdayss for toddler's The Rockridge Library used to have a Saturday morning story time for toddlers and preschoolers. I haven't gone recently, but it would be worth giving them a call.
Re: Fun things to do with babies & toddlers
Baby Bounce at the Berkeley West Branch library Weds at 7:30 pm should also be fun for all, even though 7:30 might be a little late for the babies.
