How do you handle Mother's Day?

My kids have a lot of mothers. So many that it is impossible for them to make enough Mother's Day gifts at school for all of their mothers. Heh. I've worked very hard to make sure the little kids knew that I would not have my feelings hurt when I wasn't given a Mother's Day gift. I know they love me, and they do NOT need the extra pressure that comes to them during this holiday.

A mom.
A step-mother.
Me.

That's a lot of mom. ;-)
