We haven't done much traveling with my 2 year old son, and I am looking for a great deal of advice. We have plane tickets booked in September to fly into San Francisco. It is only for 1 week. It will be my husband and I, along with our 2 year old son, and my mother. We literally have nothing planned. I would like to see the coast, but my husband would like to see the huge trees. Any and all advice would be greatly appreciated! Thank you all in advance!
