I do stay business only, though showing feelings around the kids of course. Ex "It's so great to see D6 play with ...."
This sounds like a conversation you'd have with a friend. Is that one of your goals for your relationship with your ex moving forward? My co-parenting chats focus on actionable decisions such as if/when to get the vaccine or return to school. There's nothing wrong with your interaction. I do notice LBS who want to reconcile seem to spend more time talking to their ex's about their children than LBS who have moved on, so this caught my attention and it may be worth considering your motives in going beyond friendly.
