Swaddle transition failure

Well as previously posted I attempted to try how my baby would do unswaddled.  FAIL!  lol..she just isn't ready.  She still needs that comfort of being wrapped up tight.  Which is fine by me, I wish I could feel that comfy cozy and go to sleep.  However, there is still the issue of the rolling over that is coming about.  So in my mind I figured I need to get one of those blankets made for transitioning.  The Halo Swaddle Sleepsack to be exact.  It gets rave reviews so it must be good.  I just don't want to pay the price of it.  $36.95 plus shipping seems a bit steep to me for a blanket, plus I don't even know if she will like it.  As always I go to my local online swap and shop and put an ad out looking for this Halo blanket.  With luck 1 person replied and she had 2 of them.  She wanted $10 a piece which isn't bad considering the web price on them.  So I scooped them up.  Now the one thing to remember, and shockingly I did not, my baby is a Houdini baby.  The Halo Swaddle Sleepsack is not for Houdini babies!  I put this blanket on her and she almost laughed at me as she so easily moved her arms up and out of the blanket.  So this is a reminder and a warning all in one.
1) If you're wanting to try something out with your baby always try buying used first.  That way if it doesn't work you don't feel so bad about wasting money.  Plus you can usually put it right back up on the site you got it from and sell it for the same price you bought it for.
2) The Halo Swaddle Sleepsack is in no way or form for Houdini babies.  However, I will keep it for a little longer to perhaps use it for a transitioning blanket for both arms out.  That way she can have the blanket wrapped tightly around her body but her arms will be out.  Plus she will have the added comfort of still having the warmth of a blanket.
Another lesson learned and this task will have to be postponed for a little longer.  Will try again in a couple weeks and see how she feels about things.
