Nanny Needed For 2 Children In Littleton.

We are looking for an occasional nanny/babysitter for our two children in south Littleton. Our son is 3 and our newborn daughter is 2 months. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified. We are looking for someone to come to our house for occasional date nights and helping when my husband is out of town on business (week nights and some weekends). I work from home but would need help with the children when he's out of town which would include feeding, diaper/bathroom, meals, playing, etc. We also would need someone that is comfortable around pets and very familiar with dogs. We have two dogs and one cat. One of our dogs has an aggressive bark but doesn't bite. He will eventually warm up, but will still bark anytime a new person comes around.
