Why Babies Sleep Better in Merino Wool

At Moalie, we consciously choose merino wool—not just because it's soft and natural, but because it's scientifically proven to improve your baby's sleep. Studies from renowned journals like The Lancet , the British Journal of Dermatology, and Nature and Science of Sleep confirm this.

1. Fall asleep faster, sleep longer

In a study conducted by the University of Sydney, participants wearing merino wool pajamas fell asleep faster and slept longer. This was especially true in cooler temperatures. This is essential for babies still learning to regulate their temperature.

2. More weight gain in premature babies

A study published in The Lancet found that very low birth weight babies fed lambswool gained an average of 22.7 grams per day, compared to 18.6 grams when fed cotton ( source ).

3. Less itching and better eczema

The DESSINE study showed that superfine merino wool significantly reduces eczema in young children. Parents reported less itching, less use of hormone creams, and better sleep.

4. Naturally temperature and moisture regulating

Merino wool can absorb up to 35% of its weight in moisture without feeling clammy. This keeps your baby warm and dry, without overheating – something synthetic fabrics like polyester often fail to do.

Our baby rarely slept longer than two hours at a time. Since we started using the merino wool snuggle, she sleeps more peacefully and noticeably longer. It's truly a world of difference. – Moalie customer
