I would significantly broaden the list of schools you apply to. As I understand it, unless you are a resident of oregon or washington, OHSU and UW (respectively) are almost impossible to get into (i think this may have changed for OHSU). UCSF is among the top schools in the country, and I don't think anyone can count on being accepted there, no matter how strong you application is. Your GPA is good, but not spectacular--in other words, it probably will not open or close doors for you. You seem like you have pretty good extra-curriculars, try to emphasize these in your personal statement. From the bried amount that you have shared, I would say that your most unique features as an applicant are your role as a mother and your fluency in 4 languages. Do well on the MCAT. Before we know your score on that, we can't really tell you if you are a competitive applicant, but the rest of your application seems relatively solid. Apply early and good luck!
