HT you have an everything refuser. As much as it's a complete pain in the ass, there is something to be said for a child who knows their own mind. DD has a friend who is very placid and easy and smiley, and I must admit I'm quite proud of DD for being a bit more 'knowing' and cynical.
FATE the dummy is a tricky one. It seems to help her drop-off more easily, and it definitely makes it easier to get her back to sleep (dummy in, Ewan on, shush shush shush...sleep). But I think it also causes her to wake up more frequently, she is a side-sleeper, so she relaxes, slackens her jaw, and it falls out. Then she shouts (she used to wake-up gently, with murmurs, now it's zero to shouting immediately). she doesn't cry, she's not upset, she's just furious.
She is not particularly emotionally attached to the dummy, if I tried to give it to her during the daytime she'd look at me as if I'm completely mad, more than anything it's a simple distraction so she stops using every last ounce of energy to stay awake "ooo what's this in my mouth, interesti..ZZzzzzzzzZzzzz".
The annoying thing is she is perfectly capable of taking the dummy out and putting it back in. But she refuses to because she'd rather be awake. I've caught her take it out, and very carefully, post it down the back of her cot, and then shout. As I said, she's a cynical, knowing little one.
She's much better now, her temp has been normal for 48 hours, still teething (5 and 6 coming through), but in generally quite a good mood. Being well again really helps because we can tire her out (swimming/swings/groups etc.) whereas when she was unwell, we tried to keep her warm and inside a bit more until she felt better.
We can usually tell how well she'll go down at night based on how easily she napped during the day (she has a 30 mins mid morning and 30mins-2 hours early afternoon). And yesterday and today she went down much more easily.
I just wonder why she doesn't seem to be going into a proper deep-sleep. Previously if her dummy had fallen out in the middle of the night, she wouldn't really notice. Probably sore teeth.
