Catalina, Looking for a family to share childcare with in Culver city

Looking for a nanny share for my son who will be 28 months in September. I am considering returning to teaching part-time starting at the end of August 2018. My hours will vary from week to week, but I anticipate needing someone three to four hours a day, sometimes in the morning, sometimes in the afternoon. Because of this, someone with flexibility is key. Because some days would be shorter than others, I would prefer not to host in my home. It would be easier to be able to drop my son off and then pick him up when I'm done teaching.
