On the kids: try to get in some one-on-one play time rather than start probing. When they feel strongly connected to you and can relax, they will open up. Then just listen, validate, show empathy, etc. No advice at all until you are absolutely sure that they have gotten out everything they have to say. Open ended questions are OK. Using paraphrasing to check if you understand (they'll confirm or correct you) is good. Otherwise, good eye contact. No judgment of anyone involved, and present for them. You can analyze your thoughts and reactions afterwards.
Good luck, and I hope it is just a temporary stress-related thing.
