stomach sleepers

My LO is one month old and between the hours of 10PM-730AM she will sleep solid on her back swaddled and wake for her feeds. Now between the hours of 730AM-10PM the ONLY way she will sleep longer then 30 minutes is if she is on someone. I have been struggling with getting anything done and an over tired baby most nights because  my little girl struggles to sleep during the day. Yesterday I placed her on her stomach in her bassinet and watched her constantly and she slept for two hours. Has any other mums experienced this and what did you do? I know it's not the best option but everyone parents different, I don't want to place her on her stomach at all. Xxx
