Thank you all for your comments on my last post. It was very helpful. And Ava made the unswaddle decision for me. Yesterday morning she was almost out of her miracle blanket, a.k.a the baby straight jacket, but her arms were still down. This morning she got completely out. How she managed to Houdini her way out of that, I have no idea.
Our goal with sleep training is to teach her to soothe herself back to sleep and to improve her day sleep. We have some bad habits to break. I nurse her to sleep every night and put her in her crib asleep, which is apparently a big no-no. I was of the mind set that as long as she was sleeping, we weren't going to fix what wasn't broken. Now that she's seemingly ready to go swaddle-less, we need to make a few minor changes.
So wish me luck. We could potentially have a sleepless weekend ahead of us.
