That is really inconsiderate of her. Do you feel like she thinks you are her employee? Because that happens sometimes and we have to put our foot down and make people understand the boundaries. We have a working relationship with a contract and we provide a service in our homes but that doesn't mean anybody has a right to access to our home at their own whims!

If that were happening to me I would have to be polite but blunt. Whatever makes you feel comfortable, but if I were you I would write a letter addressed to all my daycare clients and outline the parts of your home that are accessible to your clients. Use the word CLIENTS. I would include in the letter the fact that your home belongs to your family and you are sharing certain rooms with the daycare children, however parents should confine their movements to (for instance) the entrance hallway unless invited in for a special occasion.

Some people don't have common courtesy! But if you address the letter to all of your clients the offending one will get the message. If not, you will have to say it to her face. But definitely stand up for your rights and your family's rights.

Yeeesh, this makes me so mad for your family!
