My 1.5 -2 yr old RF has recently flipped over in the heat. He threw up a couple times. Ive been soaking him twice a day. Someone has recommended pedialyte for when he soaks, did that for a day and going to continue to do that. His eyes shut when he is not being soaked, and still not interested in food. This is the 4th day im pretty sure. When should i start getting worried?
