I am still learning as well so don't feel bad. I will try searching around for you but I know there are a lot of experienced people on here that will offer some great advice.
I found a few things from online and as always this isn't from my personal experience I am sorry to say but maybe until someone that knows a little more this can help.
" Remember that once pedialyte is opened it must be used within 24-48 hours. You can always make ice cubes from it to prevent it from losing its beneficial properties. Pedialyte and Gatorade do contain sugar so use it in moderation."
Here's another way if the dropper method is too stressful for her, or she wont take it up orally.
"For tonight, you can help your dragon by giving her a special soak. Buy some unflavored Pedialyte (yes, the kind for human infants). Prepare a shallow
bath consisting of 1/2 water and 1/2 Pedialyte. Soak your dragon for about 20 to 30 minutes twice a day. Reptiles can absorb the electrolytes and fluids through their vents, so make the water deep enough to cover the vent. Also, make sure you increase the temperatures to the levels I discussed above. "
I hope someone else can give you a better idea, I don't know if giving it more than 3 times a day is too much, it could be. But figured the info on freezing it might help since you don't have to give them much at a time.
