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

We are looking for a great nanny for our 2-year-old son in Duluth. I am a stay at home mom, but looking for someone to assist me with our toddlers & twins on the way. We would prefer someone who is willing to get down on the floor and play with our son, take him to parks and do activities, prepare his lunch, and handle nap time. In the fall, when our 2-year-old goes to half day school I would need help with the twins as well. We would prefer a nanny who has their own car, who does not smoke and who is CPR certified. We currently have an awesome nanny, but she is moving out of country late July. We are looking for someone to start July 27th.
