April's bad habits

April didn't sleep through the night until 1 year old.
Around 5-6 months, she started waking up once per night (not as lucky as those parents who has babies sleep through the night as early as 3 months old). That is an improvement, not great but helpful to working parents like us. Yet improvement stopped there. She persisted 1 charm per night, mostly Mommy's fault and partly due to her personality.
The routine is like this...half sleeping Mommy will pick April up from her crib (Her crib stayed in our bedroom until it's replaced by the toddler bed. MISTAKE #1, putting the crib in the same room will not encourage independent sleeping) then feed her which comfort her and put her right back to sleep (MISTAKE #2, night feeding make sure sleeping through the night will never happen!) After breast feeding, we kept a warmed bottle of milk for her night feeding. April probably won't need any night feeding by then, but Mommy didn't get the click(MISTAKE #3, Laziness and sleepiness is no help in correcting the situation) Not to mention, Daddy is no help in this arena, he will snore through the thunder (aka April's crying)
Initially, after the feeding, Mommy will put April back to her crib and that's it, we can have the peace until morning. Later on, Mommy skipped this last step and let April slept between us.(MISTAKE #4, she will hold on to this and never let go) Here's the magical moment, since that's pretty much the time April sleep through the night, she need the comfort and security from Mommy. It's not the night feeding probably, or say, it wasn't really her target. Therefore sleeping through the night by herself didn't really happen until we moved when she gets her own room. But sometimes, she will wake up at night and finds Mommy in the dark and continue her sleep.
We tried and we really tried a few times but we failed, hopelessly. We told her what's going to happen. Then we put her in bed, sang to her, told her we gonna turn off the light and she is going to sleep by herself. Then we closed the door. The thunder came and it's endless. The worst time was she crawl out of her crib, luckily we had beddings on the floor(we were trying to move some bedding to storage) so she landed unhurt, then she crawled to the door and banged on it. We have tenants at home, 2 of them(Mommy was very amazed why they never complained). We heard the banging and knew it's not right, opening the door finding her right by the door full of tear and rage. And that's the point, we knew we shouldn't try it again until we can talk some sense into her. We will try our best for our #2, but hope is not high.
Then there starts another bad habit, pinching Mommy's elbow and fingers. April hates pacifier. We never bought one, we got one from the hospital. Tried it couple times on her, when we can't calm her down. She will suck a few time then spit it out, and cried even more with anger, it's like she got cheated. But she definitely need something to help her fall asleep. Just not the pacifier or any object. Mommy needed things like that when she was young, it was a super soft blanket. Mommy likes to rub it and that helps her falling asleep. Not to April, she needs human flesh, the crease part of elbow and fingers. She will straighten your arm or your fingers to get the maximum folding and her pinch could be painful at times. This bad habit persists until now. She understand it's not good to that, but she can't help it. It's an addiction to her already. Nothing can replace the skin, no stuffed animal, toys, books, blankets, nothing. It's a strange habit to have, Mommy wonder when she will stop doing it. On another note, when Mommy told the daycare lady about this habit she had. The daycare lady told Mommy that has never happen to her and same stays true in preschool. April doesn't need anything to help her falls asleep! But when she's with Mommy, it's a different story. Mommy also tried to restrict her pinching, but so far it hasn't been successful. She knows "No elbow" but she will still try for fingers.
