Dock a Tot

Does anyone have a Dock a Tot? I'm seriously considering getting one because our sleeping situation is insane. My daughter only sleeps on us (really bad I know, but it's the only way we all get some sleep). But if anyone has this I wanted to know how it works for you! My baby is 3 weeks & likes being on her belly, so I'm wondering if this would even help. Every review online has been awesome but I'd like to know if anyone has it or something similar! Thanks mommies ☺️
