the doc said it was a combo of the heat, her being dehydrated and her not eating.
we have tried to explain to her hella times that its important to eat and drink water. when it happened i was waiting with my son and i looked over and saw her arms drop/ drop her gameboy and then go limp and drop. luckly my wife was right there and my daughter said she didnt feel good like 10 seconds before and she grabbed her before she hit the ground.
i ran over and grabbed her, at first i thought she was having a seizure (made sure she wasnt) but then i noticed she was ghost white with no color at all.
