Try wrapping your little one again which way are you wrapping ??? Arms down the side of bub or wrapping in the way the arm are covered but there up near her face? This works so well as theyre secure but still move their arms and have their hand near their face yet the wrap stops the reflex startle.. Hey i still use this wrap style with my 9 mth old on the odd occassion when he is soooo tired but just cant settle.... it works nearly everytime.

You can find the wrapping styles on line thats where i found it but i havent the link sorry

i hope this helps
I have tried both methods and she fights it all the way and only calms down once she's free! - She can be quite stubborn
