Today is Middle Child's Day. According to www.holidayinsights.com, "Middle Child's Day gives a little well deserved recognition to the wonderful and special middle child in the family."  Since a middle child is likely to feel left out, this is an excellent idea because "older and younger children tend to be more outgoing, or extroverted, and the middle child tends to be more introverted, quieter, perhaps a bit of a loner" (www.holidayinsight.com).
