Dockatot?

So because of room space at the moment my hubby and I are going to have our daughter sleep in her pack n play and set her brother when he’s born in her crib until we get him his own a few weeks after hes born. However, I’m thinking because my daughter had a hard time sleeping in her crib as a newborn and I absolutely am not going to co sleep with him, should I invest in a dock a tot? I know you’re supposed to supervise them, however since I’ll be up most of the night anyway I am not too worried especially since he will be swaddled.
