When to abandond ones principals??? (rant no2)

So, my dbg is just that, a little darling!, she's filled with energy and uses it up quickly, that means she gets very tired very soon and has no energy to eat or sit down for a story once she's hit bottom.

A few weeks ago we weened her off the pacifier (we call it dummy, so for future reference, dummy=pacifier) it went ok, it took her about a week to settle for her night time sleep without it and now she sleeps like a dream (most of the time) without it, the day naps never settled, she will scream and scream and scream so in the end I told my hubby that we'll have to give it to her, I nor her can take this any longer.

So now she'll fall asleep but wake up as soon as the dummy falls out of her mouth, I try to get her to suck her thumb but she likes to pat things and forgets to suck the thumb, though she still gets upset when it comes out and forgets that it was her thumb and she can easily put it back in again, she also is still struggling to get the dummy in properly, sometimes it works but most times it doesn't so I go in to her room over and over again, her sleep is interrupted and it turns out it's not a good enough nap.

Now she's also a bit wingy and the dummy helps calm her down, we have tried to hold it off, but her sad face just makes my insides shrink and I think, am I taking the dummy away for my sake or hers? It obviously bothers me to hear her whine and whinge, and part of me hopes that one day she'll start looking for it herself and I let her whine for while, though since she almost never finds it and puts it in her mouth herself I end up after having had her cry/whine/whinge for a while go over and do it for her....
I am worried that this bad habit is never ending, so this was me abandoning my principles, but I'm not sure to what good or bad

(my hubby reads this and looks at me, what happened to you? he says. I used to do this, as a nanny these things are so easy to deal with, no nonsense and it all works out great, maybe I should take a step back, stop letting cries bother me, enjoy the time we have while she's little and stop worrying?)
