LesleyC that has not been my experience - the little ones up to age about 5 invite the whole class but thereafter it seems to be 'best friends' (only 3 or 4) who are invited to a treat.
However, in this case it seems quite a lot of little boys have been invited and I can understand how upset you feel redf. Making a fuss and tackling the mother about it could cause a lot of friction and cause a rift between the boys.
as DH said, whilst the parents are squabbling over something to do with the children, the children themselves have forgotten the upset and are playing happily together again.
Best say nothing, don't make a big issue out of it and do something special with your DGS on that day.
