Seeking occasional babysitter for two kids, starting August 11th

Hi there, I am looking for the perfect person to watch over my two amazing kids. I need a babysitter that can come over on occasion when I have to work for my shift, normally a Friday, Saturday and Sunday. I work in the healthcare field as a nurse. My normal shift is 1100-2330, but I need coverage during the occasional day and times I have education classes. The ideal candidate is comfortable around pets; we have a sweet dog named Dean as well that will hang out with you. Just needing someone to keep my kids safe. Need to be CPR certified and First Aid trained. My kids love to be outside playing and will always have snacks prepared by me available.
