Hi.
My DD is having a joint birthday party for her 6th birthday, with her friend from school as they are born 1 day apart and they will be inviting all their mutual friends from their class.
My DD asked if she could invite one of her friends from nursery that she is still close with and her cousin, who is 6 months older in addition to the class. The other girl whose party it is, is not inviting any additional friends/family.
Due to this I have not invited the younger cousin (3 years old) as it is a joint party and there will be nobody else there his age, but I planned to do a smaller family party the day before for grandparents/aunts/uncles and cousins.
i thought that my family would understand this as it is a joint party, however my SIL is not happy and causing a fuss that he is not invited and has been excluded, even thought it has been explained that no other young children will be there and I would be having a small family party also.
Am I wrong to not invite him?
