Part time nanny for a 3y old

Part time nanny needed for our 3 y old son. Initially just a few hours in the mornings but must be able to work flexible hours. Currently job wil just entail caring and playing but may be required to do school drop offs and pick-ups and preparing meals in the future. Must be fluent in english and familiar with montessori principles and have at least 1 year experience with toddlers. No formal qualifications required but would appreciate some sort of first aid training or someone who is willing to get trained.
