Infants on the go will do well in the miniature Graco Travel Lite Crib ($100). With all the same features as a regular Pack n Play, the "Lite" version is a bit smaller, lighter and convenient. It has two settings so the baby can rest on the bottom or higher up like in a bassinet. When the pad is on the raised level, it makes for a perfect changing table, too!
