Yes, she did make a mistake and why, to go out with her friends, how is that responsible? She is 16 and should know better. I honestly don't think Fiona has her babysitting all the time. When you have no one around and need help there is nothing wrong with having your teenager babysit their siblings, it is a learning experience for them and teaches them responsibility if they can show it. All I meant by the 15rys time comment was that it is very hard raising a teenager, nothing like raising babies and younger children, it really is hard work.
