Newborn skin is thinner and more reactive than adult skin. Here is what fiber content actually changes — and what the label is not telling you.
A newborn's skin barrier is still forming for most of the first year. It is thinner than adult skin, loses moisture faster and reacts to friction and trapped heat more readily. That is why fiber content on a crib sheet is not a marketing detail.
Cotton is a natural fiber with a hollow structure that moves moisture away from the skin and lets air pass through. Polyester and poly-blends trap warmth against the body, which matters when overheating is one of the risk factors safe-sleep guidance asks parents to manage.
Synthetics feel their softest the day you unwrap them and pill over time. Cotton does the opposite: percale and muslin both break in with every wash and get noticeably softer through the first year of use.
"Cotton-rich," "cotton feel" and "cotton touch" are not cotton. Look for 100% cotton in the fiber content, and look for third-party testing. Every Bacati product is SBS tested and CPSC compliant.
Wash warm, tumble dry low, skip the fabric softener — softener coats cotton fibers and reduces the absorbency you bought cotton for in the first place.
