Haha! My mouth fell open too! You've got to promise me that you won't do this for anybody else! lol. Can you imagine the precedent you'd be setting with this client? Any time anything went wrong, she'd be right there asking you to step into the breech. You would basically be caring for two people instead of one. My gosh! You're very kind hearted, but honestly... you need to form clear boundaries. You are the daycare provider. Not the mother, sister or bff.
