I would gracefully tell the teacher what you told us. The aid needs to be appreciated too but not at the expense of your daughters feelings. If the teacher was to give the flowers to the aid she could have done it without your daughter knowing it. Tell her you didn't have the money for a present for both. Tell her how much thought your daughter put into the gift. Tell her how about how upset she is! I am sure she did not mean to hurt your girl in any way. It is a sticky issue if not handled gentlely.
Good Luck,
