Occasional Day Time Sitter Needed For Infant In Orlando

We are looking for a great sitter for our 3-month-old son, in Orlando. We are new parents and just need someone to be an extra set of hands during a couple week days a month and occasional date nights. We would prefer a sitter who has their own car, who does not smoke, who is comfortable with dogs (we have one friendly dog) and who is CPR certified. My husband works from home 3 days a week and I work from home full time, so we sometimes need someone to come help out for a few hours when we are both busy. We're hoping to do this sporadically, so we will be able to provide advance notice. We would love to have a sitter for occasional evenings and weekends, too, as things come up. W is a sweet baby and I'll do everything possible to make sure our sitter is comfortable here! Thanks in advance!
