Azer has been getting better about recognizing when the balloon may be getting a little low on water. I noticed he has way less anxiety about pulling out the button if he does it himself, since only he knows how it really feels. I am really proud of him for being able to do so much on his own!
Here is a picture of the Mic-key button with the balloon filled with water. That is what holds the button inside the stomach wall. We usually replace the button about every 6 months.
