Nanny Needed For My Children - Full-time / Part-time

We are looking for a great nanny for 3 children in San Antonio. The twin boys will need most of the help since they will be born in July/Aug. Our 6-year-old is in school, however will need someone who is capable of watching multiple children at once. We would prefer someone who could help out with light housekeeping, cooking and homework help. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified. Looking for someone hopefully long-term to add to our family. Thank you.
