If you are thinking about becoming pregnant, pregnant, or have a baby, you must check out DayOne. They offer classes, support groups, and have a retail business as well. They carry the best baby toys, gear, books, and clothing. You can join for an annual fee and get a discount on classes and clothing. DayOne was founded by 2 lactation consultants. I highly recommend using DayOne for this service. They are very professional, honest, and supportive. If you are new to SF and have a baby, the support groups are a great way to meet other women with babies.
