Does anyone have experience of this? I think it may be a sensory thing rather than health, but could be wrong.
My son has always been obsessed with drinking water. Ideally really cold water. When he was tiny it was like an urgent need. He would scream in the car if he couldn't have water immediately. He's calmed down a bit, but still has this urgent craving. He wants to drink water directly from the bath tap, or any random receptacle he sees along the way.
He goes ages without peeing and shows no other symptoms of diabetes, so I don't think that's an issue. I wouldn't worry so much if it was just in the day time, but I have no way of limiting his water intake in the evening, or during the night, without him getting really upset and screaming that he needs water. He chugs it down before bed, and has to have a non spill cup in his bed. If he finishes it during the night, he will wake me up (joy of joys!) in the middle of the night to demand that I replenish it. He says he needs something cold to cool his mouth down.
Obviously, this is making it impossible to train him out of pull ups at night, which is my main issue - along with a niggling worry that there's a problem.
I went to see the psychologist at the children's centre at his nursery, when he was still at nursery and she said that it may be a sensory thing, and that if so perhaps I could replace it with something that fulfilled a similar need, but I'm pretty stumped as to what.
The GP suggested monitoring his intake vs output, but like I say, he hardly pees during the day and at night he wears pull ups, which are usually and unsurprisingly sodden.
If anyone has any similar experience or clues I would love to hear from you!
