Re the kid she decided not to be friends with because she was too bossy and manipulative - does the kid understand this or does she think your dd is being mean and excluding her? And with the younger neighbour kid who you say your dd has a friendship of convenience so she can control the games - is that kid going to turn round in 6 months and stop playing with you dd is being bossy and manipulative.
Also the birthday parties. My son has 24 kids in the class - no way can i do a party for 24, 12 of them are boys - can't do that either. He has about 6 people he has known for years to invite so he can invite 2 or 3 kids from his class that is all. However unlike a lot of other parents i don't let him take invitations to school and i encourage him not to talk about who is coming. One person i know let he son hand out invitations at school to every boy in the class bar one (what was she thinking?). I've heard parents say they think their kid is being mean but it is up to the kid (um no).
