Sleep regression and safe sleep...

This sleep regression thing is driving me insane. I'm a true believer in safe sleep. Alone, on their back, in their crib... you know what it is. Takingcarababies newborn class helped me achieve my goals of creating safe sleep habits for my girl and she would sleep easily 10 hours in her bassinet at a time. However, the last few nights have been agony. I know a lot of you on here are going through this as well. She's been waking up literally every 45-60 minutes crying, wanting to be held only, and the second I put her down it's just a cycle of crying and not being able to sleep. So I put her in my bed. And she curled up in my chest and fell fast asleep. I was so against this but I am on day 3 of no sleep and I let her sleep there and I dozed off as well. I don't want this to become a habit. It's been so hard. I feel like every once of my patience is being tested and tried. I feel so defeated. I hope this passes soon.
