You don't expect anyone except your boss to say thank you, right? Parenting is like that. Parents expect their kids to be thankful, but we don't expect others to thank us for caring for them. Stepparents are a little different. They give out of the overflow of their hearts so it's nice when others notice what they do for their stepkids. September 16 is National Stepfamily Day. This is a good opportunity to honor stepparents and call attention to the love that's shared in blended family homes.
