Part-time daytime nanny for one 7-month old baby girl

We're a young family of three! Mom works full-time in Concord, while Dad works full-time from home but unfortunately can't look after the baby while working, and baby is a 7 month old crawler who's desperate to be up and about! We're looking for a baby-focused sitter who can keep the baby happy, clean and entertained through the day. Dad will be on hand for help if needed, and we don't expect any extra work like cleaning or meal prep! The position is part-time, three weekdays each week between 7.30 and 15.30. We also have one very placid and happy cat!
