I am moving to San Diego and had a question, bare with me? :

I am moving three hours from my current home soon, it'll be to San Diego. How would I go about trying to change my WIC place and my daughters and my doctors as well as my Medi-Cal, how would I go about moving my Medi-Cal from this area to the San Diego area?

Welcome to San Diego! I'm in Ocean Beach, love it down here  

From their website: http://www.fns.usda.gov/wic/howtoapply/whogetswicandhowtoapply.htm#Moving

WIC participants who move from one area or State to another are placed at the top of a waiting list when they move and are also served first when the WIC agency can serve more individuals. WIC participants who move can continue to receive WIC benefits until their certification period expires as long as there is proof that the individual received WIC benefits in another area or State. Before a participant moves, they should tell the WIC office. In most cases, WIC staff will give the participant a special card which proves that the individual participated in the WIC Program. When the individual moves, they can call the new WIC office for an appointment and take the special card to the WIC appointment in the new area or State.
