Nanny Needed For My Children

We are looking for a babysitter and playmate for 2 twin daughters in Anaheim. Children well-behaved. Must speak and read Mandarin fluently. Parent will be at home when babysitter is needed. Looking for children to have early exposure to Mandarin through play. We have toys, some Chinese books, etc and speak limited Chinese. Children are biracial with Chinese heritage. Have some exposure to Chinese culture but not to language. They will attend Mandarin bilingual public school in Anaheim and we want to get a head start. 7am-8 p.m. anytime that works for you.
