Cluster feeding 3 weeks

Au

My baby girl is 3 weeks and cries pretty much non-stop unless she's got a boob in her mouth. She has 0 interest in a pacifier or her bottles. (Regardless of what my mom or sister have been telling me I believe the whole "can't spoil a newborn" thing) I don't really have an issue having her at the breast all the time, I just wanna know how the heck you sleep?? 😂😅 I start dozing with her latched when we're in the bed, I have to stuff food in my face to stay awake but that only works so long before I have to TRY to put her in her crib. She suckles for a few seconds-minutes and dozes. Even when she unlatches on her own and sleeps she wakes up as soon as I set her in her crib.

Her daddy is on deployment untill the first of the month, and it's pretty much just me, the furbabies and her I'm so terrified I'll fall asleep with her in the bed and she's gonna get hurt or suffocate. I can roll with the 1-3 hour sleep cycles but she hasn't even been letting me get thar, so.... How do you sleep without endangering the little ones? 🤣😭
