I totally agree. Just because I have my own children, it doesn't make them obligated to come and entertain the daycare children. My son was six when I started doing daycare and if he wanted to come down and play with the daycare children, he could, but he didn't have to.
He didn't choose this job, I did, and I wasn't going to force it on him. The only time he had no choice was if his dad wasn't home and I was taking the other kids out. Then he had to come with us.
BUT, I actually had a mom pull her kids out of my care because MY OWN SON was able to go on OUR computer (that wasn't even near the daycare room) and her son wasn't allowed to! I couldn't believe that she would actually use this as an excuse to take them out! I told her that this is HIS home and he could go on it, if he wanted to and I'm sorry, but use of our family computer was not part of the daycare program.
Now that he is in highschool, he is glad to stay away from the daycare room, as he is not one for little children!
