I agree with the others that 6.5 months is still tiny, and even without teething/illness, she will want and need you in the night.
Sleep deprivation is horrible, and I think most of us have been there/are still there!
I had a nightmare with DD going down for naps for the first 6 months. Managed to convince myself she didn't need the comfort, as she wasn't a newborn any more. That she was being manipulative and awkward. All thanks to the fact well meaning people were telling me she shouldn't be STILL sleeping in the sling, and should be learning to "self-settle". I was miserable.
I then came to the realisation, that my little baby was falling asleep with me there and then was finding herself alone in her room without any concept of how she got there. Or I would put her down expecting to sleep, and she had no idea that's what I wanted/needed her to do because the usual cues weren't there. She was too little to get it. Once I realised all this, it was much easier to make my peace with it, acknowledge that it wouldn't last forever and was happy to carry her whilst she slept until she was ready to sleep by herself. Which in the end was only about 1 month on from this crisis point!
I don't think you should beat yourself up for 'pandering' to her. You're just responding to her needs. I too don't buy the "rod for your back" idea. I got that a lot, because we opted to babywear and have always been baby-led (no routines, always respond to her cries, did baby led weaning etc etc). I was going to create a monster child, who would be clingy & demanding. She would only eat cake because we let her self-regulate. She would never learn to walk because she was always carried....etc etc 
We've now got a contended, happy 18 month old. She is secure and relaxed, and will happily go to other trusted adults. She has a balanced diet, and will eat pretty much any food. She walked at 12 months, and actually walks more than all her friends as I let her down from the sling when she wants! We still respond to her cries, and in turn she trusts us explicitly.
Now all that may not be for you, but what I'm trying to say is...Follow YOUR instincts. Not anyone elses. Do what feels right for you and your baby, and you'll be a damn site happier than if you're trying to live up to other peoples expectations.
