Occasional Sitter For 6 Month Old

Hi. I'm looking for a long-term occasional sitter for my 6-month-old baby girl, Mila. It would be for shorter periods of time like 1-4 or 5 hours max and likely increase as she gets a little older. No exact times, just when I have something to do without her -- so definitely looking for someone with flexibility! We are located in Lancaster so someone nearby would be great. I'm ok with either dropping her off or in my home. I'm a single mom who spends all my time with Mila. Enriching her with new experiences, play, etc. is important. Mila loves the water and takes weekly swim classes. She also loves her dog, Cali who's an American Bully and a complete sweetheart. .
