Thank you so much for all of the support and words of wisdom. Right now the kids are having free-play and I am sitting here on the computer watching. Not feeling guilty.
I just started typing all of the things that are bothering me with the 2.5 year old and I deleted it because this is a public forum and I don't want to be recognized. However, it helped me to see that I definitely have some resentment built up (against the parents) as well as a couple of trust issues with the parents. I think this adds to my overall stress factor. It's so hard maintaining line between having our clients as friends that we chat with at pick up and drop off, etc., caring about and for their children and the business relationship.
