It does seem very coincidental that this started to occur after the separation.
I can only give you my personal experience. My nephew took to wetting the bed for a good long time after his mum and dad divorced when he was 8. His brother who was 10 didn't have the same reaction.
Once everything had settled down (12 months or so) and the little lad had come to terms with it abit more, this went away by itself.
The fact all physical evaluation has come up ok points to a reaction to trauma.
Please bear in mind that although this split is in the best interests of the adults involved (and even if it is in the best long term interest of the children) this is still very traumatic for them. They need to understand how this is going to work for them and will still maintain the relationship they had with both parents now they are no longer living together.
I know we are quick to seek professional psychiatric help, and maybe it is necessary, but sometimes we expect children to act like mini adults and incidents like these maybe remind us they are still children.
