Ellie beat the Miracle Blanket

So I have been sleep-training Ellie for the past couple of weeks.  We are using the Ferber method loosely, and letting her cry it out for short amounts of time.  She was doing great, some nights better than others, but then she figured out how to flip over onto her stomach IN her swaddle!  Ay mamacita (as my nanny would say).  It scared me because Ellie would flip over and face-plant into the mattress without turning her head to the side.  So we decided it was time to wean her off her swaddle so that if she flipped over, her arms would be free to help her push up.  Well, as it turns out, Ellie loves her swaddle and wouldn't sleep without it.  She cried for 1 1/2 hours when I removed her swaddle. :(  So now we are slowly trying to wean her off of it for her naps during the day by leaving one arm out.  At night, we are loosely swaddling her so that she can get her arms out.  But we're sleeping her back in her bouncy seat until she doesn't need her swaddle anymore to sleep.  Then back in the crib she goes.  This is a picture of how I found her one morning...pretty much the swaddle was just a fashion accessory.
