Can I give ORS to my 8 months old daughter as she sweat's a lot due to hot weather and may be she's dehydrated? If yes how much shall I give?

Hi, Normally paed will only prescribe ORS when LO having diarrhea, to increase body's salt. For normal hot day, you can always ask your daughter to drink more plain water, or you can make more juices for her consumption. This will maintain the hydration in her body.
