OH okay! I'm sure you are tired, having a sick baby is exhausting, not to mention that you just when through this with Jaden too

Hope you can get some rest tonight!
Her getting water on her own is fantastic

If she continues drinking and eating well, the Gatorade should be tapered off. I'd feed her a little more food in a while and then see if you two can snuggle up and get some rest. Set your alarm for a couple of hours from now and just check on her and see if you can tempt her with some more grub
Hugs to you all
