Nanny For 1 Year Old, Full Time From Mid January

We are looking for a nanny to look after our 1-year-old boy, full time from mid January to mid/end May, while our family is visiting Berkeley for a sabbatical. He is an outgoing and happy toddler and loves outdoor activities and singing. We're looking for a reliable and caring person to look after him in our home while we work, keep him safe and engage him in play and stimulating activities. Meal prep needed (but no housework, other than putting away his things after using them etc). We also have an 11-year-old daughter. She will be in school during the day and is generally pretty independent, but might need school pick ups. The main job is looking after our 1-year-old though!
