Baby sleep tips

Tips on how to get 7 week old to sleep?

I can't put her down without her waking up, ever. Not even at night. She won't fall asleep if I leave her no matter how tired she is. She will cry until her face is purple and not breathing when I out her down during the day.

She knows day from night at this point but we still do dark room at night and light room during naps. I put her down every second I can but she will only sleep for 10 minutes if she's not on her belly.

Kinda losing my mind here.

I can not afford a snoo so please don't even suggest that.
