There are no state or federal laws in Massachusetts that require a babysitter to be a certain age. The recommend age is 13 for children over the age of 4. Under the age of 4 it is recommend the babysitter be at least 14. Keep in mind this is a recommendation only.
In the end the state feels a parent knows what is safe for each individual child and allows the parent to make the call as long as the child has a form of communication for emergency's ( A Phone) and the child is mature enough to handle the situations.
Keep in mind while there are no laws that stipulate a age the child protection services can intervene if they feel the child is not mature enough to babysit.
