Babysitter Needed For 2 Children

We're looking for a loving, responsible and reliable sitter to care for our 2. 5yr old and newborn sons. Responsibilities for my toddler would include preparing his meals (breakfast and/or lunch) changing him, taking him for walks, light laundry and some small housekeeping tasks such as vacuuming and his dishes/dishwasher. Responsibilities for my newborn include feeding him his bottles, changing diapers and giving him lots of snuggles! We also have two other children, ages 6 and 7 who attend school and occasionally we may need 1-2hr of help when they return home on days when my husband and I may still be working. This may including preparing snacks for them and keeping them busy with activities until we get home. I work from home so my schedule varies but it will be an avg of 25-30hrs/wk. Approx 7:30am-3:30 p.m.
