Babysitter Needed for my Children

We are looking for a reliable and caring babysitter/nanny/mothers helper for in-home childcare while I work from home. Schedule is flexible (TBD), but generally a few hours a day, about 4 days per week. We have a 4-month-old baby boy and are looking for someone experienced with infants who is comfortable providing care, playtime, and basic baby routines while I am working in the home. Ideal candidate is responsible, attentive, and has prior infant experience and references. CPR certification is a plus.
