Anyone use this??

I feel like it would really help my 9day old son who hates being flat on his back (prefers to be elevated cz of gas) and who also HATES to be swaddles cz he likes his arms above his head. I literally stay awake with tons of coffee and just stare at him all night to make sure he stays breathing cz I have to keep him in his swing or boppy for his own comfort but he really needs to be in his bassinet/pack n play so I can get some sort of sleep but one review said that 12 babies have died of suffocation using this 😭 I’m a hot mess. I really feel like it would help and it’s cheap enough AND it’s something i could get today but I’m scared now
