Yeah, probably not wording it well at all. Oh well out it comes.
Basically without trying to make accusations, DS has said that my X's new DP (step dad) has slapped him once. That part seems clear, in the way it came out of DS - by accident in what we were playing. And that he is adamant it happened once not twice or three times or all the time.
What is not clear what else happened or why it happened. DS adds extras, I wouldn't call it embellishments, more of what should have happened. Like "after that then DS got angry and shouted and threw them down with his tail" (Really that wouldn't be DS except in his wishful mind and he doesn't have a tail).
XsDP is a touch on aggressive and short tempered. I have also heard him shouting at DS on the phone, but up to now assumed it was just verbal.
But there are 100 explanations like, could have been playing, pretending, or on the other extreme loss of temper. So I of course wouldn't want this escalating, but equally can't ignore.
DS is now also adding the extra heroics to many a story. The extra tensions is with DS Mum and new DP. Since (long story) she has effectively reduced her role to a vassal of her new DP, she has also become far more agressive in dealings with me. Subject of mediation and more perhaps.
DS doesn't like going to mum's house anymore. (again part of that long story). Until now, I've just assumed it was standard telling off, change of Mum's attitude etc. (Might still be)
Anyhow I can't ask his mum, since well it will just cause fireworks and newDP has already very early on indicated that DS tells mistruths (I never understood why). And then the nature of question is also an emotive one, which is why I tried leaving of the detail.
Now a one off incident that his mother stopped is well done and dusted. But a one off incident that his mother simply stood by is more of a concern. Also if it is not a one off .....
So after all that, really was trying to see if there are any tips in getting the truth (and just the truth) out of a 4 year old, without the heroic stands, and without leading him into saying something that never happened. If there is a way of course And a 4 year old's memory is not the best, and then if I keep asking he is likely to say what he thinks will get me off him.
Hence the question for tips
