Help!!!! Sleep deprived

My LO is 6 weeks old and she just likes to sleep on my chest, if I lay her down on her bassinet she only stays there for 1 hour max. I try to make sure she is sleeping for at least 30 minutes and then try to put her down on her bassinet but it never lasts long. I usually stay up all night because I’m just terrified of falling asleep with her on my chest, I’m so tired !! Doyou guys have any tips and tricks to help me ?
