Babysitter needed for infant starting September 24th

Looking for a day-time as-needed sitter, starting 9/24 @10am-1pm.
I'm looking for someone to babysit my 6-week-old on a regular but as-needed basis a couple times a month, about 2-4 hours at a time during business hours, plus an occassional evening or weekend. My partner works from home but can't do any child care while on the clock. Located in south philly very close to a BSL subway stop. We have an old cat but no expectation to care for him or do any tasks outside of infant care. Please be fully vaccinated, have gotten this year's flu shot (or plan to), and have no contact or travel to the PA counties with measles outbreaks.
