My LO falls asleep beautifully in her swaddle (Velcro kind) but wakes up and fights it all night. She doesn't cry, her eyes are closed but she's wrestling, grunting and completely working herself up. She gets too hot in the process as well. We have tried multiple different types of swaddles but had no luck. We also tried not swaddling or swaddling her arms up but she won't fall asleep. The only peaceful sleep she gets is skin to skin on me.

Anyone else having issues? Any ideas? I hate to hear her stressing.
Re: Swaddle fighting
Regarding gas, I don't think so - it continues forever until either the fuss is about to turn to crying or I can't take hearing her stress anymore.
