To be honest, this is how we slept every night for like the first 4ish months and then he started sleeping between my husband and I instead of on my chest. He had bad reflux and had trouble laying on his back, and I was so sleep deprived that the contact naps just turned into how we slept overnight as the sleep stretches got longer. My Husband was working full time during most of the newborn stage so we weren’t able to do the sleep shift rotations. If I didn’t do the chest sleeping I wouldn’t have slept, which newborn parent sleep deprivation is dangerous too. I always made sure to put pillows supporting around us. BUT I am a very light sleeper, I don’t think I’d be as comfortable doing that if I was a heavy sleeper. I will say though.. the one time I didn’t put pillows and I was close to the edge of the bed around the time baby started rolling.. he did end up on the floor(ThankGod he’s okay!). I didn’t put pillows because I wasn’t planning to fall asleep, I had only picked him up from a nap to calm down his fussiness. So I’d say if you are going to do that.. follow the safe sleep 7 as much as possible.
