Thanks guys. We get them in 7 day blocks. I already asked the kids and they both said they don't want to talk to her. I will still call and let them chat for a few minutes. They will speak the truth to her about anything she asks.
This week, we have gone to amusement parks, water parks, game center, swam, built massive forts inside my place and I've cooked for them (something I've never really done before). My youngest was even afraid to try a cookie because "it may be better than mommy's". She eventually tried it and loved it. Hopefully W keeps it civil and doesn't lose her cool. She has attempted to get me to do less with them to "level the playing field" so the kids have easier transition back to her. I told her to shove it, politely of course....
