4yo DS has not been drinking enough recently, and I have spoken to his preschool teachers about this and asked that they encourage him to drink, but I'm picking him up every day to find his water bottle still in his bag, completely full.
Most mornings I remind him myself, literally right in front of the teacher, to drink lots but I can't go in the building with him and make sure he gets it out the bag.
Several times now he has had a high temperature, stomach/headaches in the afternoon because he is so dehydrated.
I've had the same problem with his glasses. With the rush to get out of the house for the bus in the mornings, we kept forgetting DS's glasses, so I started putting them in his school bag and asked that the teacher remind him to put them on at school, but I generally find them still in his bag and he says he hasn't worn them all day.
I know that he has to learn to do these things himself at some point, but am I being unreasonable to expect that at his age he could be prompted?
