The crib I used almost from the time he was born, but I also had the
pack n play, because it was
portable and made traveling with him/having him with a baby sitter SO much easier. I could just bring the pack n play, it sets up fast, I didn't use the bassinet part, I just put him all the way down on the bottom...I think I spent $150 on the pack n play, and about the same on the crib. It was well worth the money I've spent...I've used them both so much.
