Ways to celebrate

"Middle child syndrome" sounds scientific, but modern psychology research is much more skeptical of birth order than the popular idea suggests — genes, peers, and personal experience carry far more weight than where you fall in the sibling lineup.

Celebrate by:

  • Reaching out to a middle child in your life and telling them specifically why they matter.
