Feed or soothe

I have a 7 month old baby that is still waking through the night which in itself stresses me out. But what should I be doing when she wakes overnight? Feeding or just soothing back to sleep? I read somewhere BF babies can continue to need night feeds up to 12 months so I do not want to withhold milk if she needs it. But equally I always feed her upon waking and she suckles for a very short amount of time then just goes back to sleep?
