Today I responded to Caroline's shrieks to find her clawing at her foot and crying. "My foot is hurting 'cause it's got bugs in it!" She had ripped her sock off and was genuinely panicked.
From her position it didn't take me long to figure out that her foot was asleep. After a short foot massage and a long explanation she was happy to go back to her play. I was grateful it was an easy fix.
