Part Time In-Home Nanny Needed For My Newborn/Infant

I have a newborn who requires care while I work from home. He will need to be monitored while sleeping and fed during his wake windows with light activities like reading and tummy time. As he is only 1 month now, as time progresses, activities will progress as well as well as longer wake windows. He is exclusively on breast milk which will be readily available each day for bottle feeding. Naturally this comes with diaper changes as well. The schedule ideally will be in the afternoons from 12-4 or 5 depending on my day. certain days I will need care from 8-12. The schedule will be sent in on Fridays for the following week. We also have a Tuxedo cat named Frank. He does not require care, only a few rubs and a treat here and there. My husband and I appreciate someone who has experience with newborns.
