Nanny Needed For My Children

I have a kind of a shy 3-year-old son who tends to be pretty clingy and a outgoing flamboyant independent 6-year-old daughter. We usually start of our day getting ready eating and taking a walk around downtown somewhere. They have activities at home they keep themselves occupied with as well love going to the pool in the apartment. I honestly just need a few hours to sleep during the summer due to me working overnight or may need them watch while I run some errands throughout the day. Overall, its looking about a 4 to 7 hour babysitting gig.
