DD (who is 10) loves her granny but my DM can be very overwhelming and does not understand DS (who has SEN) at all. When DM comes with both DD and DS I can't discipline DD (because it's always DS fault) and she winds DS up.
DM bombards me and DD with messages - I just mute her, or don't reply, but DD isn't mature enough to ignore things (she also can't ignore DS winding her up).
DD is more keen to see DM and spend time with her than DS or DH/I are. We're thinking of arranging for her to go and stay for a few days, and also hoping DM might see that DD is not the little angel DM thinks!
But I do want DM (who has form for getting upset over perceived slights, it's not just me/DD) to understand a) that DD is a child and can't be expected to show all the communication niceties that adults do b) we will discipline her if she's being rude, it is not DD's job to manage DM's emotions around people finding her overwhelming and c) DM can be a bit too much.
