Choking sounds at night

My 6 week old has reflux and is very gassy. During the day I have it under control and she seems ok even when she naps. It’s only at night that she makes these really scary choking gurgling sounds all the time. She’s sleeping around 2-3hrs a stretch at night but she keeps making these sounds. She also kicks her legs around a lot in her sleep. I don’t know if this is normal or if she’s sleeping well.

Anyone else facing this?
