One piece on, and she is ready. Gerber's Long-Sleeve Romper for baby girls is made from 100% cotton drop needle rib with room to move from head to toe. The 2-way zipper opens top or bottom so diaper changes take seconds, and soft looped trim at the neck and pocket adds a sweet detail. Soft, breathable, and gently stretchy for every wiggle and crawl. Machine washable. Gerber quality.
