Hi, M.!
These are the descriptions I've seen:
A Sitter's primary responsibility is to care for the child, including entertaining the child, making sure the child is fed according to parents' instructions, and generally providing for the well-being of the child/children. Unlike a nanny, a Sitter's responsibilities typically do not extend to other household and extensive child-related responsibilities (e.g., there is usually no light housekeeping, meal preparation, transporting children, running errands, etc. involved). Such additional responsibilities may certainly be negotiated with a Sitter, but are not typically part of their job description.
Typical Salary - Pay for Sitters may vary anywhere from minimum wage to $10/hour or more and depend on the Sitter's experience, number of children to be cared for, region of the country, etc.
Nannies are professional, in-home childcare providers. They can often be an affordable alternative to daycare/childcare facilities, depending on the salary range being offered and especially if there is more than one child to be cared for. Additionally, having a nanny provide individual and experienced attention and caring to their child/children in the comfort and safety of their own home can offer many families a greater peace of mind than with daycare.
Job Description - The main role of a nanny is to provide a safe, caring, nurturing and stimulating environment in which a child (children) can develop. General responsibilities include caring for a child/children and most things related to that child's care. Each nanny position may have slightly different responsibilities depending on the family requirements, the age(s) of the child/children, and other factors, but typically include such responsibilities as helping children get dressed, administering meals, cleaning up after children, helping children with schoolwork, organizing and engaging in activities with children, etc. Other requirements may or may not include light housekeeping (beyond picking up after children), transporting children to and from school/activities, preparing meals for children and/or family, grocery shopping, running errands, child and/or parents laundry, etc.
A nanny may work anywhere from a few hours/week up to 12 hours/day depending on the requirements of the family.
Typical Salary - Salary ranges for Nannies are typically from $7/hour to $20/hour or $200/week to $800/week and depend on whether it's a live-in or live-out position, the number of hours per day or week, the nanny's experience and education level, the number of children to be cared for, region of the country, responsibilities, and a family's affordability level.
Day Cares will provide a structured environment for your child and many more. They will also have a structured curriculum.
You may want to check out gonannies.com. You can search their database to see how many meet your requirements, and then decide if you want to join, which will allow you to post your requirements and get in contact with people who are looking for positions. I have done this, and have gotten a lot of responses. I'm having a harder time because I only need someone 10 hrs/week and most of them want a full time position.
I hope this helps!
