I found this exercise:
http://forums.abrsm.org/index.php?s=&showt...ndpost&p=167329...really, really helpful!
Don't beat yourself up about it - you still haven't been playing that long and it does take time for the embouchure to cope up there (I'm still working on it, myself....

!)
DON'T spend ages and ages/beat yourself over the head with it. As you have discovered you will tire your embouchure out and also stress yourself out, which is totally counter-productive!
Move slowly into the top register, a little at a time. Don't go pushing yourself up into the stratosphere till the foundations are well and truly laid.
It IS hard not to pinch, esp when you feel that's your only chance of getting up there, but if it IS the only way you're getting up there then you need to keep working a bit lower down I think, because it probably is (I think...) partly because your lips are not quite "there", and trying to go beyond where you're able to with good embouchure will probably just cement bad habits rather than help you. If you *have* to pinch to get those notes, then you'll end up pinching just because that's "what you do". Have patience with yourself!!

I guess that's really why I was asking about other flutes... wishing I could blame the flute and that replacing it would solve the problem, but I know that's not gonna work. sorry.
Don't apologise, I think we all have times like that (I do....

) - it'd be nice to think that we could sound like professionals if only we had the right flute

And I totally agree with Andrea - you're doing great, don't be so hard on yourself! The 3rd register is really difficult just to get reasonable, let alone to get really in tune and with good tone etc. (tis the bane of my LIFE!) It's a pain in the proverbial, and you're not the only flautist who's ever gone "argh

" with frustration at it, honest - *to my knowledge* I'm not sure I've ever met anyone who *hasn't* had problems with it at some point.
Give yourself a pat on the back for doing really great so far, and treat yourself with kindness and patience. It WILL come
