Nanny Needed - Full-time / Part-time

We're looking for someone to help care for our infant, who will be around 3-6 months old. I'll be working away from home 1 or 2 days and need some help during the day, approximately 8am-3 p.m. The job involves the usual baby stuff: giving bottles, changing diapers, putting her down for naps, and playing/entertaining her. We'd love to find someone who speaks Spanish and could speak Spanish to our baby, but that is definitely not a requirement.
