Why Chemical-Free Matters Extra for Preemies
Premature babies have thinner epidermis (up to 50% thinner), underdeveloped skin barrier, higher sensitivity to fragrance and chemical residues.
When to Switch Brands
Most NICUs discharge babies at 4-5 lbs. Continue hospital brand 1-2 weeks, then transition to chemical-free bamboo.
Special Considerations
Umbilical cord care: most preemie diapers have a cut-out. Fragile skin: change every 2-3 hours. Temperature regulation: preemies lose heat faster.
