Full time nanny to a toddler and baby

Me and my husband are both teachers. We have a nine year old and a 2 year old, and one due in May! We will need care starting in August. Take care of our two year old and infant sons during the day while we are at school. Responsibilities would include playing with them, feeding, and putting down for naps. Start time would be 7am to 4 on most, with the exception of meeting after school.
