My dd is 12 this is her first year playing schools sports. She has played little league forever and never had any major problems. Well she had her first day of volleyball tryouts yesterday and they did run them harder than what she is use to. She started throwing up (sugar was great and no ketones) after the running portion and of course this freaked her out. She hates to throw up. After she caught her breath she was fine. She loves sports but I know that she is not going to be able physically to do this every practice. I do feel like once she gets use to this she will stop vomiting. For those of you that have children in school sports do they require the same amount of running from you d child and if so what do you do when they get low and cant run. Like I say this is the first time for schools sports and in little league she just took a break whenever she needed to. Any advice would be greatly appreciated.
