X pen is large enough for them to run arround abit. i love mine for outside at the park or in my back yard. You could still put the crate in there, open, with a cozy blanket to curl up in put a ptty pad down on the opposite side and i like to leave food and watter out all the time. Your baby can't get out but will have all the things it needs for a day alone. If I have to leave Copper alone I set it all up in my bedroom for him. I would highly recomend one.
