| Is she clenching her teeth? External symptoms might include a bunchy looking chin.
Check to see that she is not rolling her lips inwards. Just have her form the embouchre away from the horn without saying anything beforehand; that way she won't try do do what she thinks you want instead of what she normally does. That'll give you a good visual idea about what she's doing, and allow you to correct accordingly.
I've seen kids try to "squirt" sound when they make their first attempt. If she can't sustain her sound for any length of time, this may be the case. Have her begin first by proclaiming a loud "Ho!", then replace the word "ho" with a buzz.
