Spit up

So no matter how long it’s been, 10 mins an hour it doesn’t matter, as soon as I lay my newborn on her back she spits up, a ton!

Only when I lay her down in her bassinet, or whatever.

A google search suggested propping her head up a little bit, but I feel like that’s not safe. She’s not even 2 weeks old.

Suggestions? Her doctor doesn’t seem concerned by it because she’s not losing weight, but it’s more of i dont want her uncomfortable and covered in spit up all the time 😩
