Falling asleep with baby!!

My baby will be 7 weeks old tomorrow and she’s been fighting sleep so hard. I sometimes bring her into bed with me and hold her and rock her until she falls asleep. My problem is that sometimes I fall asleep with her on my arm or beside me in bed. I know this is NOT safe. I need tips or advice on how to help her fall asleep faster or how to stay awake myself or how to put her in her bassinet without waking her up. I feel like she only sleeps soundly and stays asleep in my arms. *picture example of one way she will fall asleep*
