Your home of organic premature baby clothing

At Little Mouse we know how sensitive premature babies’ skin can be. That’s why many of our premature baby clothes are made from organic cotton. Naturally soft and breathable, organic fabrics are kinder to delicate skin and less likely to trigger eczema, dermatitis, or allergies. They’re also mould resistant and antimicrobial, giving parents extra peace of mind.

What premature baby clothes a NICU baby can wear will depend on it's stage of development and it's current care. It's best to ask the medical team.

What clothes will a premature baby wear?

What premature baby clothes a tiny baby can wear will depend on it's stage of development and it's curent care i.e. is baby in the hospital NICU or SCBU or not. This will determine if a premature baby just wears an incubator vest or premature baby sleepsuit, hat, mitts, tiny baby snowsuit, etc.

Ultimately, it's most important that a premature baby's temperature is regulated and it is comfortable. Dressing with premature baby clothing should cause minimal disturbance, and layering items is recommended when baby is out of the incubator.
