 [ Symptoms ] my 3 year old just had his tonsiles removed and he refusing to drink can giving him a bath help with hydration  he will crunch on shaved ice but i do not think he is getting enough to drink he is eating baby food which i assume has some water to it but not much he is in a lot of pain and we want to make sure he gets enough fluid will letting him soak in a bath help at all i know drinking water or gatorade etc is best but looking for some alternatives [ Disease ] unfortunately humans cannot absorb water through the skin so it is back to the shaved ice again sucking on popsicles or just taking tiny sips through a juice box straw hopefully his doctor gave him something for pain a little tylenol with codeine eliier will help him a great deal but you will need to get someone to call in a prescription for him if his throat hurts less he will be more likely to drink signs of dehydration include a lack of tears a dry mouth and a reduction in his urine output
