Betty is the best! She is a mother of 3 grown children and a grandmother. We've had her with our family since my daughter was 4 months old and she has been perfection. Never late, always reliable, takes my daughter to the Zoo, Academy of Science, Golden Gate Park, and to play groups at the community center. She has other nanny friends so my daughter is always playing with others. She will even do babysitting on weekends and evenings and has been there for us on short notice. The. Best.
