4 year old fell in gymnastics class.

Elicia

My husband called to tell me that our daughter fell in her gymnastics class while doing a straddle on the bar. She was upside down and landed on her head. He said that she didn't cry, but she did say it hurt a lot. She is moving her neck and there was a mat under the bar. He's still worried.

Should I call a nurse helpline tonight or wait until morning to call her pediatrician?
