Desperately need advice, Newborn refuses to sleep on back in bassinet

I have a four day old newborn who refuses to sleep on back in bassinet. The first night at the hospital, anytime I put her down she would cry. I swaddle her and lay her down in bassinet but something about being on her back with no support, she hates it. I ended up having the spend the first night with her in my arms the whole time. I stayed awake and anytime I dosed off, I forced myself to stay awake. The second night it was the same thing. I feel my eyes getting so heavy and tired but she will not sleep anywhere else than my arms. As soon as she’s put on her back in the bassinet, she starts stirring around and crying within a minute. By day three I needed to sleep, I had someone come over during the day to watch baby so I could just sleep a few hours. This person managed to lay baby down on her stomach in the bassinet. This was the first time my baby finally got sleep somewhere other than my arms. But I know she is not supposed to be sleeping on her stomach. I am absolutely terrified of SIDS, hence me continuously forcing my self to stay awake all night. I can’t risk her sleeping on her stomach if I’m not watching her the whole time. Today I put her in her baby swing, She was swaddled and had a thicker blanket loosely around her as well. This provided support for her body which helped her to sleep for a little while but once again, I was watching her the whole time because I know the loose blanket being behind her could result in suffocation. I also know a baby obviously can’t spend the night sleeping in a swing. I cant put a pacifier in her mouth either because I don’t want nipple confusion before breastfeeding has been established. Since she’s been born I’ve gotten a total of maybe 10-15 hours of sleep. I feel worried that this lack of sleep will cut down on my milk supply. I also feel worried if I don’t get her sleeping on her back soon, she’ll never learn. I find myself sobbing out of tiredness, lack of answers, and disappointment in myself. I’m so tired, I don’t know what to do anymore. I try explaining it to pediatrician and others but I don’t think anyone fully understands. I just keep being told to swaddle her, they don’t understand she won’t sleep without support around her whole body and head. They don’t understand I am literally awake all night not allowing myself to sleep. I am lost on what to do at this point. via /r/pregnant https://ift.tt/YwIjksV
