They get very strong around your DD's age!! Our DD was only swaddled until 11 weeks when she kept getting out of them and then getting tangled in them, we stopped bc it wasn't safe anymore! (she could even get out of the miracle blankets!!)but she's a houdini She still had the startle reflex quite strong at that age but she got used to sleeping in a sleeping bag instead soon after anyway.

Sounds like she might have had enough. Good luck!
