Ugh, I feel your pain. If you look one post below yours you'll see mine...
Anyway, thought I'd give some ideas.
First, yes it will end, in time. My pediatrician told me that we all inherit sleep personalitites from our parents, so some kids are better sleepers than others, and all we can do is guide and influence. So keep that in mind. That said here are some thoughts.
1) not wrong to give extra attention to a sick kid for sure, just be sure that you're not AP. Don't rock to sleep. Try pulling up a chair and patting until calm, settled, and then leave. You can do a kind of modified Wi/Wo when sick too where you stay and pat/rub, but then leave when calm and settled. You don't have to use a chair.
2) Ditch that early milk, she's waking for it now and honestly, unless your doctor tells you otherwise, she can wait until a more decent hour for her milk. Here's how I ditched the early milk (thanks to Mari's suggestion): Get a non-spill sippy with water and put it in the bed at night. Tell DD where it is, and that if she needs it, it's right there. In the AM when wants milk, go in, offer the sippy (you have to talk through this, i.e. here's some water honey, it's too early, time to lie down, etc.) if that doesn't work, which it won't at first, do Wi/Wo, offering the water in the same way, until she goes back to sleep. Then, in the morning, don't get her the milk right away. Change her, dress her, then give her the milk...even wait until breakfast for it, offering water first thing instead.
3) Give meds for the teeth. Those molars hurt like an SOB, and you'd wake up too. Think of it like getting really bad cramps, you can't sleep and all you want to do is take more advil, so you do, and you sleep! If DS is really teething badly, I'll give a dose at his bed time, and then 4 hours later go in and give another one while he's sleeping, just to keep ahead of the pain.
4) using Wi/Wo. If you're going to use it, use it all the time. So, you need to use it at bed time as well as in the night and for naps. It's super effective, and I highly reccomend it. But, the key is really consistency.
Hope it helps, it will get better eventually, but you've got to stick to a plan. And be prepared that it might get a LOT better, but might never be "perfect" for a long, long time. (((((((((((hugs))))))))))))
