I co-parent my DS with my ex husband. DS is 8 years old. His paternal grandmother also cares for him quite a bit as she is retired and in good physical shape.
Me and exH still go on our respective holidays without DS (we have family holidays too but good to get away just adults only!)
When Exh is away, there is never an issue - I just get on with it.
I let exH know months ago about my 1 week holiday today. He works and his mum doesnt drive, so I made arrangements to make sure that DS was collected from school (my parents are taking time out of work to do this) and drop off to one of their houses. I sent through the plan weeks ago and hadn't heard anything from exH to say it wasnt ok.
Fast forward to today, I have the grandmother calling me complaining to no end. Apparently exH hadn't told her about anything about this, and I should have instead.
AIBU to expect that if DS is in the main care of his dad that week, that ExH should be making sure he agrees to any arrangements and confirms with people involved, especially his own mother?
