I think mentioning the swearing was good, boundries. So the kids push her buttons, she can't take the stress with kids! Interesting, my wife has never had to watch our S. for a whole weekend without help, I have done it numerous times. It can wear on you especially when you are trying to find happiness with what you do and not who you are!
Try not too stress over little stuff, second it is all little stuff. I agree with ping as well in your sitch and it was outlined in mine. Backoff on compliments and see if she comes fishing for some. I hope your weekend goes well.
