Last night I sat in my son's bedroom and held him in my arms as he cried in pain. His hip hurt and he couldn't find relief from it. I tried desperately to help. I rubbed his hip, wiped his tears and whispered comforting words. We tried different positions, distraction and holding him close, but it wasn't enough. I couldn't take the pain away. Not for the first time I felt powerless, frustrated and overwhelmed with sadness for failing to protect him from harm.
