What it is: The super-soft, lightweight sleepers from Baby Gap's First Favorites collection are made of 100% cotton and zip down the front for diaper-changing ease.
Why we love it: "You get so many 'outfits' as gifts, but your baby spends a lot of time sleeping! I often give a one-piece sleeper in the 3- to 6-month size, since babies outgrow the 0- to 3-month size so quickly -- and I like clothes that open in the front so you don't need to struggle to put it over your baby's head!" –Lisa Moran, senior parenting editor, iVillage
