Theo's Story
Theo was born at 28 weeks, weighing just 600g, and spent 101 days in the NICU in Manchester. His mum Rachael founded Simply Preemie because she couldn't find premature baby clothes that truly fitted him. Every piece in our range is chosen with that experience in mind.

Frequently Asked Questions
What clothes does a premature baby wear?
Premature babies need specially designed clothing that is soft, gentle, and perfectly sized for their tiny bodies. Preemie baby clothes are usually made with delicate fabrics, easy fastenings, and designs that allow for medical equipment if needed, helping premature newborn babies stay comfortable and protected in their early days.
How do I choose the right size clothes for my premature baby?
Choosing the right size preemie baby clothes usually depends on your baby’s current weight rather than their age. Most premature baby clothing is sized by weight ranges, such as micro preemie, early baby, and tiny baby sizes. Soft, well-fitting clothes help keep premature newborn babies comfortable while allowing room for movement and any medical equipment if needed.

How many clothes does a premature baby need?
Most premature babies only need a small number of well-fitting preemie baby clothes at first, usually around five to seven essential items such as bodysuits, sleepsuits, and hats. Because premature newborn babies grow quickly and may spend time in hospital, it’s best to start with a few soft, comfortable pieces and add more as needed.

If your baby is in hospital, it’s important to understand the NICU clothing rules before bringing in garments
Should I choose organic cotton clothes for my premature baby?
Organic cotton preemie baby clothes can be a great choice because they are made without harsh chemicals and are especially gentle on delicate, sensitive skin. Soft, breathable fabrics help keep premature newborn babies comfortable and reduce irritation during their early days. Learn more about the benefits of organic clothing for premature babies in our detailed guide.
