ElanVannin, So sorry to hear about you GGD, I do hope that she gets the help that she needs.
Our middle GD is also 11 years old, she is our "special" one, with problems. I know how challenging it's been for our DS & family, as no school since the lockdown started.
We thought we had problems, but nothing to compare with you & your family.
Thinking of you with kindness.

What treats did your grandparents give you?
