Had a two year old come back after a weekend visiting with the grandparents not wanting to put weight on one of her legs. Turned out to be a "toddler stress fraacture" across her foot. They figure it was caused from jumping down off the fireplace matle at grandma's which all the cousins were doing but part way through she didnt' want to play any more and they just assumed she was tired but when the mom dropped her off in the morning said she was still acting weird to keep a watch on it. By noon it was obvious she had no intentions of walking for the day and mom took her in. Doctor started by saying oh just inflammation in hip and gave her muscle relaxer/anti-inflammatory meds. By Wed she was no better and this time mom took her to emerg and demanded an xray. Poor kid came the next day in a cast.
