Super soft for all-day wear and all-night comfort. Meet The Billie Long Sleeve Zip Romper, made from cotton with a cool cotton feel that's gentle on baby skin. The two-way zip makes nappy changes quick and easy, even when they're wriggly, while the fold-back foot muffs keep little toes toasty warm. Turn-back mittens for smaller sizes add extra coverage. Perfect for daytime cuddles and middle-of-the-night feeds.
