Bed sleeping

My girl is only 3 days old.. she refuses to sleep longer than 20-30 minute increments in her bassinet and still healing from delivery it’s very hard for me to get up 2-3x an hour. I just need some sleep! So we decided to move baby changing pad onto mattress, put her in sleep sack with blanket on her feet, on our California Kong’s size bed.. sides are raised on pad so no rolling for her. What do you guys think?
