No, that’s mostly fair, and it wasn’t my point to state that sending a kid to their room equals torture. But I hope you can understand that witholding water is not a good thing, ever. Kids might not express (or fleven feel) the thirst. And that can definitely be a bad thing. Take into account possible emotions that involve crying or just warm weather etc. and they could easily get dehydrated. Losing just a few % of bodyweight water can be negatively impacting already.
