Baby sleeping in boppy?

So idk why but my 1 month old baby loves to sleep in the boppy. Nowhere else.. or not even flat in the basinet .. just in that boppy… idk why… i know it says dont sleep in there for a long period of time.. but my newborn loves to in the night only… is it ok? I mean she in a good position not strunch in there ., she can breathe good and okay. I was just wondering if any moms out there had babies that loved the boppy sleeping in there at night…
