I understand it is difficult to suddenly find yourself having to 'manage' someone, especially someone in your home, and that you don't want to have a confrontation. If you do want to try giving her a chance, put your expectations in writing, e.g. a checklist or schedule for the day. You can handle it diplomatically by saying that you are afraid perhaps you weren't clear on your expectations, and if she has any issues with what you've detailed, she should let you know. Say that you want open communication and to make sure that everyone is happy with how things are going.
However, if she is just 'ok' with your kids then go with your gut instinct. For $20 an hour I'd expect a high degree of professionalism, a strong rapport with the kids, ability to take initiative, etc. She sounds like she's coasting and it will probably not get much better even if you do talk to her.
What's your point? (OP said the sitter was "ok" with the children.)
