LO grunts all night. help?

Kara
Because she's trying to get her hands/arms up and out of the swaddle. She's wiggling around and grunting. She'll stop for a few minutes but starts right back up and lasts all night. If I see she's got her hand free I'll wake us up and re-swaddle and nurse til she falls asleep again. If I pick her up and hold her she stops. In the afternoon she does this and I'm so tired that I end up putting her next to me in bed. Now I'm afraid of starting a habit where she'll only sleep next to me and not alone in her bassinet. I don't know what else to do. I'm not good at making a tight swaddle and watching YouTube videos on it doesn't help at all. They use dolls for their demo. Not a crying, won't stop moving their limbs baby. I've tried leaving her arms out and that doesn't work. She doesn't like her legs loose. So basically nothing I've tried works except holding her. She's 2 weeks. I just want to be able to put her down to sleep alone and not start bad habits of cosleeping.
