Sitter Needed For 2 Children In Miami - Coconut Grove To Be More Specific

We are looking for a great sitter for 2 children in Miami. I am looking for someone to come once or twice a week - no set schedule - someone I can regularly call on for babysitting. Sometimes the kids have off from school and we would need someone and you would be who we called. We do have a dog so someone who is comfortable with dogs is a big plus. We also have a pool in the back yard so someone comfortable with a pool / possibly go swimming with the kids is a big plus especially when it's warmer out. Our older one is a good swimmer and can go in herself - our younger one cannot yet swim on his own and is in lessons and loves it but cannot go in by himself. I look forward to hearing from you! Please note - this is not a full time position.
