Babysitter Needed for my Children - Full-time / Part-time

We are searching for a nanny to come watch our infant son at our house. Our son had open heart surgery on May 1 and has been hospitalized twice since then. We are worried about him attending our elder sons daycare center as we think he needs 1:1 care until he gets stronger and makes it through this cold/flu season. We imagine this role would start on/around September 8, and tentatively wrap up around the spring (April/May).
