Mine is too, same age, wakes several times in the night for feeds back to sleep, we ended up with her in bed with us again last night (though she's teething too). We had the same thing with ds, now 2 1/2, were in despair and exhausted, did controlled crying with him aged 9 months, learned lots and lots about sleep cycles and sleep habits then, and swore we wouldn't get into this situation again - but we have!
I have nothing against CC, it worked wonders for us with ds (and have done it with dd to an extent a month or so ago to get my evenings back), it's just too disruptive to the whole family to do it in the middle of the night. So we are going with the flow for now; I am not bothered by the broken nights this time round, at the moment.
As for whether it will go on forever? well I doubt she'll still be doing it at 14 ... I'm sure they'll grow out of it eventually, just depends whether that 'eventually' is before or after it's been going on too long for you. My bottom line is, if it works for you, stick with it. If it stops working, if you start getting really tired or resentful, I'd say that's when to think about changing things.
