The Cocooi™ All-in-One Growsuit is made from 100% superfine Merino wool in two sizes for Newborns to 3 months. Our Newborn sizing is ideal for small or premature babies.

The Cocooi™ All-in-One Growsuit design features include:

  • Cross-over neckline so fabric stays clear of baby’s face when they twist and turn
  • Pouch bottom for easy access to dress baby and change nappy. No fiddly buttons, ties or dome/poppers.

Depending on your baby and surroundings, the Cocooi™ All-in-One can be worn on its own as well as for layering under the Cocooi™ Newborn Sleep Bag and Cocooi™ Swaddle.

The benefits of Merino wool include:

  • TEMPERATURE REGULATION. Nursery room temperatures can fluctuate during the night causing a baby to wake up. Merino’s unparalleled ‘breathability’ means no clamminess next to the skin, creating a perfect micro-climate around the body and helping regulate a baby’s body temperature before it can properly do this itself. Merino will keep your baby warm in the cold and cool in the heat and help prevent overheating, a common problem for newborns.
  • COMFORT. Our Merino is superfine, luxuriously soft, light and non-itchy. It is also hypoallergenic, helping babies with sensitive skin and eczema problems.
  • 100% NATURAL. Wool is the least flammable of fibres and the safest to have next to your body. It is naturally self-extinguishing and, unlike synthetics, it won’t melt and stick to skin. The material also retains less odour and nasty smells, thus reducing the need for frequent washing. But it is machine-washable and very easy to care for

Lovely and cosyReview by Nony
Beautiful colours and material. Initially I found these dufficult to get my babies legs in, without any poppers or buttons, but with practice it becomes quite quick and easy. My daughter is 6 weeks old and there is plenty of room for her to wear them now and grow into. She looks beautiful and cosy in them and wears them under the standard Gogo sleeping bag, which we also love, as we wanted to find an alternative to the polyester filled sleeping bags. The fact that she sleeps in natural materials reassures me. (Posted on 19/02/2017)
