These tops are a practical addition to a newborn baby's kit. Made in NZ by The Baby's Room, the merino fibre makes this top suitable for all times of year, worn as a cooling singlet on its own in summer, or its non-bulky design makes it great for layering in winter. The merino allows the skin to breathe, is itch-free and keeps baby warm. The envelope neck is easy to pull over baby's head and there are no fiddly domes. Machine washable. Size guide: 000 = 0-3 months, 00 = 3-6 months, 0 = 6-12 months. As babies vary dramatically in size, this is only a guide.
