DS (4) is at his nursery school 2x a week (he goes to another nursery the rest of the week). The invites for parties get left on a school board so I noticed this morning that there were two cards for two children that are in the same group of friends than my son. I think I even recognised the handwriting of the mother.
Anyway, I know children can choose who they invite to their parties, I know he will not be always invited, I know that my DS didn't want to invite everyone to his party either, even some that I thought were close to him, etc etc etc etc etc but I still feel bad and somehow hurt 
How do you get over this?
(yes, he is my first and only child
