Yes, DS' first 6 teeth coincided with the 8-10 month period (well, 8-11 months actually). It was hell. Then, I kid you not, that 6th tooth popped through and he slept happily with one wakeup for a feed. I went back to my own bed for a whole month (nearly) before we started the next lot of teeth.
The big problem is when there are underlying reasons for teh wakings - and some kids are just super sensitive to discomfort or developmental changes etc - then there really isn't much you can do if you can't address that particular problem. Ie, routines etc won't make any difference.
Hope the necklace helps!
