Busy family in need of a FANTASTIC, energetic, caring nanny

Hi, we are looking for an energetic, conscientious Nanny for our 3 children, ages 3, 5 and 7 years old. The two older kids are in school full-time, so most of the care will be for my 3 year old. Light housekeeping, food prep, but most important is the care of the children. The right person must be independent, take initiative (ie, know what to do and when) have excellent communication skills, creativity, sensitivity, but also know how to take charge when needed. We are a busy family and sometimes plans, circumstances, etc., can change quickly. Our kids are active and busy and we need someone with strong discipline skills and experience. We also have a family dog - no walking necessary - but perhaps feeding her when/if we forget or are out late. Serious applicants only!
