To give an explanation for my question: My husband and I tend to "forget" to drink, especially on busy days and then need to catch up later in the day. Which, I would suggest, also happens to other people. But it is far worse with our two kids, who are 6 and 8 years old. Since about 3 years I need to take extra care of their daily water intake, otherwise they simply wouldn´t drink. To the extend that kid A started to fake laughing to hide that he needed to clear his throat, because it was so dry. And kid B starts getting headache and dark circles around the eyes. At that point they still do not drink without me pressuring them to. It has become a bit better since I implemented a habit tracker for both of them to drink at least 4x 200 ml per day (they do not hit that goal every day). As long as they are at home a lot, it´s at least controllable. But it becomes an issue when there are several consecutive days being at their friend´s homes for example. So back to my question: Is there a underlying trigger for thirst/water intake? How can sufficient water intake get disrupted? And are there maybe conditions for which this issue is common for? Thank you in advance, Carina
