'How to wrap text around button in Kivy?

I have three buttons (one column, three rows) in a GridLayout. The text on the top of the button is centered but when it is too long it extends past the screen. How do I wrap it? Current code is:

self.add_widget(Button(text="", text_size = (None, self.height), halign = "center", valign = "center"))

for each of the buttons.

Setting

text_size = (None, self.height)

as an arg to the Button constructor does not set up a binding. It just sets the text_size to the values at the moment that the Button __init__() method is executed. So the text_size gets set to (None, 100) and stays that way (the default height of a widget is 100). If you want to actually have such a binding, you must either use the Kivy language, or set up the binding yourself. Something like this:

        butt = Button(text="", text_size = self.size, halign = "center", valign = "center")
        butt.bind(size=self.resize)
        self.add_widget(butt)

def resize(self, butt, new_size):
    butt.text_size = new_size
