Nanny Needed - Full-time / Part-time

Hi! I am looking for some reliable, experienced backup babysitters for my daughter when I return to work. I have a full-time nanny and want some people on hand for when she is on PTO or out sick. I work from home, so I will be available for exclusive breastfeeding during the day. Work day is usually 8-5. I am looking for someone who is fully vaccinated (flu, Covid, TDap, MMR, etc), infant CPR trained, and experienced. This will be a screen-free household (for her) and she loves reading her books and contact naps. Must be a non-smoker. I plan to do some paid trial hours over the weekends in August and September (or late July) to get everyone used to each other.
