I think at 7 they are still figuring out what is really important to them. DD played select soccer (year round) and travel softball both until she was 11 (last year). We had a few scheduling conflicts, but nothing too major. She would always choose softball over soccer, and it wasn't really fair to her soccer coach or team. On top of that my oldest boy was getting to the age where he wanted to get more involved in sports, and it was a logistical mess for DW and myself. She was a great soccer player, but gave it up to focus more on softball, because that is what she loves to do. That being said she does run track in the spring and took intramural archery last winter at her middle school.
