Operation: Lose the swaddle

Back story - We swaddled Charlie all the time during the first week or so after she was born. She would break free of it pretty often. I gave up on it and just let her sleep in footed pjs. Around 5-6 weeks, we started using the swaddleme blankets. They were a tad big for her, but I think right around the time we started using those was when she starting sleeping through the night. They have been a Godsend of us.

Now in the past week or two, I have noticed 2 things - 1) Charlie is growing out of the swaddleme blankets (1 of them doesn't fit at all anymore); 2) She has been tossing and turning more at night (she used to just lay there so still that I had to go check on her constantly). So is it time to break the swaddle? I know I'm going to have to eventually. Part of me wants to go find these blankets in a bigger size, but I told myself we would break her at 4 months - that's in 10 days! I'm kind of terrified. I think we have had maybe 2-3 bad nights of sleep since I started back at work, and those were spaced out. I don't know if I can make it a full week or 2 or 3 with no sleep. I know some of you moms never even swaddled and your babies did fine, but I'm scared my little bug is dependent on it now - or maybe I'm the dependent one. I don't know. Part of me is wondering if I should just try it out tonight since tomorrow is Saturday, and I can nap if I need to. 

Come on ladies - I know you have advice for me!!! :)
