I would prefer to employ the services of a babysitter sitter who is ATLEAST twenty years of age. Legally, any citizen who is above eighteen years is considered an adult in my country. However, having passed through teenage, I can safely draw the line at twenty. I have seen and heard of so many cases where a teenager was given a task to take care of a toddler but somewhere along the way, a party came up and the babysitter left the kid unattended. Teenage is a very tender age because hormones are also very active.
